Gnuastro 0.19 released

posted by Roy Schestowitz on Oct 24, 2022

Dear all,

I am happy to announce the availability of GNU Astronomy Utilities (Gnuastro) version 0.19. It is packed with many exciting new features and bug fixes (see below).
Gnuastro is an official GNU package, consisting of various command-line programs, C/C++ library functions and Makefile extensions for the manipulation and analysis of (astronomical) data. All the programs share the same basic command-line user interface (modeled on GNU Coreutils). For the full list of Gnuastro's library, programs, and several comprehensive tutorials (recommended place to start using Gnuastro), please see the links below respectively:
https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html https://www.gnu.org/software/gnuastro/manual/html_node/Tutorials.html
The full list of improvements in this version is available in the NEWS file within the source, and also in [1] below. The new features are so exciting/useful that Pedram (author of the newly added Warp features) has recorded a video to show the tip of the iceberg in the Warp and ConvertType programs. Please watch it to get a hands-on feeling of the power of these new capabilities using SDSS and J-PLUS images (and go the manual for the rest!):

[1] Noteworthy updates in Gnuastro 0.19 (released on October 24th, 2022)
** New features
Book: - Two new sections added to the "General program usage tutorial" for describing how to prepare a FITS image for high quality publication (in PDF), and drawing vector graphics marks from a catalog over it (for example to show your selected galaxies in the field of view). The use the newly added features of ConvertType.
Arithmetic: - Added new type operators and physical constants. All are also available in Table's column arithmetic also). - e: Base of the natural logarithm (no units). - pi: Fraction of Circle cirumference to diameter (no units). - c: speed of light in vaccume (in units of m/s). - G: Gravitational constant (in units of m^3/kg/s^2). - h: Plank's constant (in units of J/Hz). - au: Astronomical Units (in units of meters). - ly: Light years (in units of meters). - avogadro: Avogadro's constant (in units of 1/mol). - fine-structure: Fine structure constant (no units). - counts-to-sb: convert counts to surface brightness (mag/arcsec^2). - sb-to-counts: convert surface brightness (mag/arcsec^2) to counts. - mag-to-sb: convert magnitudes to surface brightness over an area. - sb-to-mag: convert surface brightness to magnitudes over an area. - New operators that are specific to Arithmetic: - collapse-median: collapse input dataset by calculating the median along the given dimension. - collapse-sigclip-std: Collapse with sigma-clipped standard deviation. - collapse-sigclip-mean: Collapse with sigma-clipped mean. - collapse-sigclip-median: Collapse with sigma-clipped median. - collapse-sigclip-number: Collapse with number remaining after sigma-clip.
ConvertType: - It is now possible to draw vector graphics marks from a catalog over the output PDF images. The following options have been added to ConvertType for doing this. See the "General program usage tutorial" for a fully working example. --marks: name of table containing mark information. --markshdu: HDU of table if file given to '--marks' is FITS. --markcoords: name or number of two columns containing coordinates. --mode: if the coordinates are in 'img' (image) or 'wcs' (RA/Dec). --markshape: name or number of column containing the shape of each mark. --markrotate: name or number of column containing rotation of each mark. --marksize: name or number of column containing the size of the mark. --sizeinpix: interpret the values in the size column as pixels. --sizeinarcsec: interpret the values in the size column as arc-seconds. --sizeinarcmin: interpret the values in the size column as arc-minutes. --marklinewidth: name or number of column containing mark's line width. --markcolor: name or number of column containing mark's color. --listcolors: List all the 140 available colors, and show the colors on 24-bit (true color) terminal. --marktext: name or number of column containing text under each mark. --marktextprecision: number of decimals to print as text when the text column (given to '--marktext') is floating point. --markfont: name or number of column containing the font to use for the the mark text (given to '--marktext'). --markfontsize: name or number of column containing the size of the font to use for the mark text (given to '--marktext'). --showfonts: build a demo PDF with one page per font to show the various available fonts on the system. --listfonts: List the names of the available fonts on the terminal. - It is now possible to select the color of the border of images produced in vector graphics outputs (EPS and PDF) with '--bordercolor'.
Fits: --pixelareaarcsec2: print the image pixel area in units of arcsec^2 to standard output. Among other things, this is useful in creating a surface brightness image using the new 'counts-to-sb' operator of Arithmetic. --pixelareaonwcs: Ouput an image with the same number of pixels as the input. But each pixel's value shows its area on the sky (in degrees-squared). This area is calculated after accounting for distortion, projection or rotation. Implemented by Pedram Ashofteh-Ardakani. --edgesampling: extra sampling along each pixel's edge used to configure the output of '--pixelareaonwcs', similar to Warp.
Statistics: - Linear and Polynomial least squares fitting are now available and very easy to call on the command-line. They are wrappers over the respective least squares fitting functions of the GNU Scientific Library. The interface is pretty simple, like the example below: aststatistics table.fits -cX,Y,Yerr --fit=linear-weighted It is also possible to estimate values and errors of the fitted model on a new X axis. A complete example has been added to the newly added "Least squares fitting" section of the book (under the Statistics program documentation). Please see that tutorial to easily use this feature. The following new options have been added to the Statistics program for this purpose: --fit: the model to use. Currently the following models are supported: linear linear-weighted linear-no-constant linear-no-constant-weighted polynomial polynomial-weighted polynomial-robust --fitweight: nature of the "weight" column (default: standard dev). --fitmaxpower: maximum power of X in polynomial models. --fitrobust: weight function to use in the "robust" polynomial model. --fitestimate: File name, or number to estimate the fit on. --fitestimatehdu: HDU containing table in file given to '--fitestimate'. --fitestimatecol: Column containing X axis values for '--fitestimate'.
Table: - It is now possible to customize the format of floating point numbers in the plain-text outputs: when output is printed on the standard output (command-line) or in plain-text files. The following new options have been added for this new feature: --txtf32format (or '-f'): Format of 32-bit floating point columns. This can be either 'fixed' (for fixed-point notation) or 'exp' (for exponential/scientific notation). --txtf32precision (or '-d'): number of digits following the decimal-point of 32-bit floating point columns. --txtf64format (or '-p'): Format of 64-bit floating point columns. This can be either 'fixed' (for fixed-point notation) or 'exp' (for exponential/scientific notation). --txtf32precision (or '-B'): number of digits following the decimal-point of 32-bit floating point columns.
Warp: - Can correct distortions (with any standard recognized by WCSLIB) and simultaneously align the image to the coordinate system. When no named linear operation (like '--rotate', '--scale' or etc) is requested, Warp will go into this mode. It is highly customizable through the following options. See the "Invoking Warp" section of the book for more. This feature has been written by Pedram Ashofteh-Ardakani. --center: RA, DEC of the center of the central pixel of output. --width: Width of output in degrees or pixels (see '--widthinpix'). --widthinpix: interpret values of '--width' as pixels. --cdelt: Pixel scale of output ('CDELTi' keywords in FITS). --ctype: Coordinates and projection algorithm. Default: RA/Dec and Gnomonic or 'TAN'). --edgesampling: extra sampling of pixel polygon to account for strong non-linear projection or distortion effects, when necessary. --gridfile: warp the input to the exact WCS and pixel grid of the file given to this option. This is very useful when matching images from differetn surveys. Using this option, you can also insert distortions in an image (for example on a mock image, to make it match an observed exposure with dithering+distortion). --gridhdu: HDU containing image to be matched in '--gridfile'. --checkmaxfrac: visualize the Moiré pattern of the warp in the second extension of the output. This is the maximum fraction of a single input pixel's area in the output pixel. When the output pixel scale is similar to the input, the Moiré pattern can cause varying artificial smoothing of the noise level. See the newly added "Moiré pattern and its correction" section of the book for more on its basics and how to reduce it in your outputs. - List of WCS projections available in WCSLIB 7.12 (and therefore in Gnuastro's Warp): AZP: Zenithal/azimuthal perspective. SZP: Slant zenithal perspective. TAN: Gnomonic (tangential). STG: Stereographic. SIN: Orthographic/synthesis. ARC: Zenithal/azimuthal equidistant. ZPN: Zenithal/azimuthal polynomial. ZEA: Zenithal/azimuthal equal area. AIR: Airy. CYP: Cylindrical perspective. CEA: Cylindrical equal area. CAR: Plate carree. MER: Mercator. SFL: Sanson-Flamsteed. PAR: Parabolic. MOL: Mollweide. AIT: Hammer-Aitoff. COP: Conic perspective. COE: Conic equal area. COD: Conic equidistant. COO: Conic orthomorphic. BON: Bonne. PCO: Polyconic. TSC: Tangential spherical cube. CSC: COBE spherical cube. QSC: Quadrilateralized spherical cube. HPX: HEALPix. XPH: HEALPix polar, aka "butterfly". - List of WCS distortions available in WCSLIB 7.12 (and therefore in Gnuastro's Warp): TPD: Template Polynomial Distortion. SIP: Simple Imaging Polynomial. TPV: Polynomial distortion for Gnomonic (TAN) projection. DSS: Digitized Sky Survey. WAT: Chebyshev or Legendre polynomials for TNX and ZPX projections.
astscript-fits-view: --ds9colorbarmulti: show a separate color-bar for each image in DS9. By default this script will show a single color-bar for all the images to help save space on the monitor when there are many images.
astscript-psf-stamp: - sub-pixel warping is applied to ensure that your coordinate is at the center of the central pixel of the output image. This results in a _major_ improvement when estimating the center of the PSF. --nocentering: disable sub-pixel warping when creating the PSF stamp. As described above, the sub-pixel warping is critical for the central part of the PSF, but for the outer parts it is statistically negligible. So to avoid slowing down you pipeline, you can disable sub-pixel warping with this option. --snthresh: if given, the value to this option is assumed to be a signal-to-noise ratio (S/N) threshold and all pixels below that S/N will be masked. This is useful because we are often forced to stack stars of differing magnitudes. While the fainter ones are good for the inner parts of the star, they degrade the stack's outer parts. With this option, the fainter stars won't harm the outer parts.
GNU Make extensions (in a Makefile) It is now possible to use custom Gnuastro functions in GNU Make, using its extension facilities with Dynamic libraries. GNU Make is a very powerful workflow manager that is also used for data analysis (not just for compilation). With the Gnaustro Make functions, (astronomical) data analysis becomes even more easier and faster. In the following, you can see the first set of such functions (they all begin with 'ast-'). For more, see the newly added chapter in the Gnuastro manual. - ast-version-is: will return '1' if the running Gnuastro has the given version (argument of this function). This can be used to ensure reproducibility in combination with Make's conditional features, see the minimal working example in the manual. - ast-text-contains: will return space-separated words within a larger list that contain a certain string. The to-contain string can be anywhere within the words of the larger list. - ast-text-not-contains: will return space-separated words within a larger list that DO NOT contain a certain string. The to-not-contain string can be anywhere within the words of the larger list. - ast-fits-with-keyvalue: takes a keyword name, a list of keyword values, a HDU and a list of FITS files. It will return only those FITS files that have the requested value(s) in the requested keyword of the requested HDU. - ast-fits-unique-keyvalues: takes a keyword name, a HDU and a list of FITS files. It will return all the unique values given to that keyword within the FITS files.
Library: - GAL_CONFIG_HAVE_PYTHON: non-zero if Python3+Numpy features included. - GAL_CONFIG_HAVE_GNUMAKE_H: non-zero if GNU Make extensions can be made. - gal_box_border_rotate_around_center: width of box after rotation. - gal_color_id_to_name: return the name of a color from its ID. - gal_color_in_rgb: return the fraction of red-green-blue in a color. - gal_color_name_to_id: return the ID of a color from its name. - gal_dimension_collapse_median: collapse input along dim. using median. - gal_dimension_collapse_sigclip_mean: collapse with sig-clipped mean. - gal_dimension_collapse_sigclip_std: collapse with sig-clipped STD. - gal_dimension_collapse_sigclip_median: collapse with sig-clipped median. - gal_dimension_collapse_sigclip_number: collapse with num. after sig-clip. - gal_eps_shape_id_to_name: return the name of a shape from its ID. - gal_eps_shape_name_to_id: return the ID of a shape from its name. - gal_fit_name_to_id: Convert string name to ID of fitting model. - gal_fit_name_from_id: Convert ID of fitting model to string name. - gal_fit_name_robust_to_id: Convert name of robust weights to ID. - gal_fit_name_robust_from_id: Convert ID of robust weights to name. - gal_fit_1d_linear: linear fit of input columns. - gal_fit_1d_linear_no_constant: linear fit with no constant. - gal_fit_1d_linear_estimate: estimate a linear fit on a new X column. - gal_fit_1d_polynomial: polynomial fit of input columns. - gal_fit_1d_polynomial_robust: robust polynomial fit of input columns. - gal_fit_1d_polynomial_estimate: estimate a polynomial fit on new X column. - gal_fits_unique_keyvalues: extract all unique values to a certain keyword in many files. - gal_fits_with_keyvalue: select FITS image with a certain key value. - gal_list_data_select_by_name: select a dataset from a list by its name. - gal_list_str_cat: Concatenate (append) list to a space-separated string. - gal_list_str_extract: Extract space-separated tokens to a list. - gal_python_type_from_numpy: Convert Numpy's type id. to Gnuastro's. - gal_python_type_to_numpy: Convert Gnuastro's type id. to Numpy's. - gal_txt_contains_string: Check a certain string within in a larger one. - gal_units_counts_to_sb: SB from counts, zeropoint and area. - gal_units_mag_to_sb: surface brightness (SB) from magnitude and area. - gal_units_sb_to_counts: counts from SB, zeropoint and area. - gal_units_sb_to_mag: magnitude from SB and area. - gal_warp_pixelarea: return image of same size, but with area on sky. - gal_warp_wcsalign_init: initialize the WCS aligning structure. - gal_warp_wcsalign_onpix: Per-pixel filling of output. - gal_warp_wcsalign_onthread: function to give to pthreads. - gal_warp_wcsalign: high-level function to align input by its WCS. - gal_warp_wcsalign_free: free the contents of the WCS aligning structure. - gal_wcs_free: free a WCS structure that is created or read by Gnuastro.
** Removed features
Statistics: --refcol has been removed because it breaks the modularity principle (given that it is the job of Gnuastro's Table program to limit rows from a larger table based on many different criteria). The output of Table can be directly piped to Statistics to achieve the same (and much more feature-rich effect).
Warp: --align: has been removed. This is because aligning an image (while correcting for any possible distortion) is now the default behavior of Warp (when no linear operations have been requested).
** Changed features
Book: - The "General program usage tutorial" section is now the first section of the Tutorial chapter, since it introduces the tools at a more basic level. The "Sufi simulates a detection" (which was previously first) has been moved to the fourth section.
Warp: - The short format of the '--centeroncorner' option has been removed. The '-c' is now the short format for the new '--center' option to Warp.
astscript-psf-scale-factor: --widthinpix: new name for the old '--stampwidth' option. This was done to have the same name to a similar option in Crop and help in remembering.
astscript-psf-stamp: --widthinpix: new name for the old '--stampwidth' option. This was done to have the same name to a similar option in Crop and help in remembering.
Library - gal_eps_write: two new arguments have been added to draw marks, and to set the border color. - gal_pdf_write: similar to 'gal_eps_write'. - gal_fits_hdu_open: new argument to optionally exit program if HDU couldn't be opened. - GAL_TABLE_DISPLAY_FMT_FIXED: new name for GAL_TABLE_DISPLAY_FMT_FLOAT since it corresponds to the fixed-point notation of printing floating points in plain-text (the '_FLOAT' suffix was too generic and unclear).

[2] Lzip has better compression ratio and archival features compared to the `.gz' or `.xz' formats. Therefore Gnuastro's alpha/test releases are only in this format, but for historical reasons we also include `.gz' tarballs in the official releases. If you don't have Lzip (you can check with `lzip --version' command), download and install it from its webpage:
https://www.nongnu.org/lzip/lzip.html
If Lzip is present and you use GNU Tar, then the single command below should uncompress and un-pack the tarball:
$ tar xf gnuastro-0.19.tar.lz
If the command above doesn't work, you have to un-compress and un-pack it with two separate commands (or use a pipe to feed the output of the first into the second: `lzip -cd gnuastro-0.19.tar.lz | tar -xf -'):
$ lzip -d gnuastro-0.19.tar.lz $ tar xf gnuastro-0.19.tar
[3] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this:
gpg --verify gnuastro-0.19.tar.gz.sig
The signature should match the fingerprint of the following key:
pub rsa4096 2018-12-08 [SC] 52B0 4484 D806 C90D CB52 7249 71E8 9901 2D17 4B66 uid [ unknown] Mohammad Akhlaghi
If that command fails because you don't have the required public key, or that public key has expired, try the following commands to retrieve or refresh it, and then rerun the 'gpg --verify' command.
gpg --recv-keys 71E899012D174B66
As a last resort to find the key, you can try the official GNU keyring:
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg gpg --keyring gnu-keyring.gpg --verify gnuastro-0.19.tar.gz.sig
[4] To get the base64 SHA256 checksum, you can use the command below (assuming you already have the 'openssl' command-line program). Just note that an extra '=' is printed as the last character that you should ignore.
cat gnuastro-0.18.71-c982.tar.lz \ | openssl dgst -binary -sha256 | openssl base64 -A
[5] This tarball was bootstrapped (created) with the tools below. Note that you don't need these to build Gnuastro from the tarball, these are the tools that were used to make the tarball itself. They are only mentioned here to be able to reproduce/recreate this tarball later.
