Gnuastro tutorial at ADASS (Astronomical Data Analysis Software & Systems) 2021
Mohammad Akhlaghi,Raul Infante-Sainz,Zahra Sharbaf
Gnuastro is an official GNU package of a large collection of programs to enable easy, robust, and most importantly fast and efficient, data analysis directly on the command-line. For example it can perform arithmetic operations on image pixels or table columns/rows, visualize FITS images as JPG or PDF, convolve an image with a given kernel or matching of kernels, perform cosmological calculations, crop parts of large images (possibly in multiple files), manipulate FITS extensions and keywords, and perform statistical operations. In addition, it contains
programs to make catalogs from detection maps, add noise, make mock profiles with a variety of radial functions using monte-carlo integration for their centers, match catalogs, and detect objects in an image among many other operations. Gnuastro is written to comply fully with the GNU coding standards and integrates well with all Unix-like operating systems. This enables astronomers to expect a fully familiar experience in the building, installing and command-line user interaction that they have seen in all the other GNU software that they use (core components in many Unix-like operating systems). Gnuastro's extensive library is also installed for users who want to build their own unique/custom programs.
