SUMMARY:SMACK 3: GNU Astronomy Utilities (Gnuastro)
DESCRIPTION:SMACK 3: GNU Astronomy Utilities (Gnuastro)\nDr. Mohammad Akhla
 ghi, Raúl Infante-Sainz, Joseph Putko\n\n \nGnuastro is an official 
 GNU package that is currently maintained at the IAC. It is a large collect
 ion of programs to enable easy, robust, fast and efficient data analysis d
 irectly on the command-line. For example it can perform arithmetic operati
 ons on image pixels or table columns/rows without having to write programs
 , visualize FITS images as JPG or PDF, convolve an image with a given kern
 el or matching of kernels, perform cosmological calculations, crop parts o
 f large images (possibly in multiple files), manipulate FITS extensions an
 d keywords, and perform statistical operations. In addition, it contains p
 rograms to make catalogs from detection maps, add noise, make mock profile
 s with a variety of radial functions using monte-carlo integration for the
 ir centers, match catalogs, and detect objects in an image among many othe
 r operations. Gnuastro is written to comply fully with the GNU coding stan
 dards and integrates well with all Unix-like operating systems. This enabl
 es astronomers to expect a fully familiar experience in the building, inst
 alling and command-line user interaction that they have seen in all the ot
 her GNU software that they use (core components in many Unix-like/POSIX op
 erating systems). In this SMACK, we will introduce Gnuastro and demonstrat
 e a selection of its commonly used features. Relevant links are as follows
