Random #Debian Astro package of the week is python3-pyraf. PyRAF is a command language for running IRAF tasks in a Python like environment. It works very similar to IRAF CL, but has been updated to allow such things as importing Python modules, GUI parameter editing and help. It can be imported into Python allowing you to run IRAF commands from within a larger script.

Random #Debian Astro package of the week is iraf-dev. IRAF is the "Image Reduction and Analysis Facility". The main IRAF distribution includes a good selection of programs for general image processing and graphics, plus a large number of programs for the reduction and analysis of optical and IR astronomy data.

This package contains the IMFORT Fortran/C programming interface, and the full SPP/VOS programming environment in which the portable

Random #Debian Astro package of the week is iraf-xdimsum. XDIMSUM is a package for creating accurate sky subtracted images from sets of dithered observations. While the observations need not be in the infrared, the dominance of the variable sky background in infrared data requires the dithering and recombination of many short carefully sky subtracted exposures to produce deep images.

Random #Debian Astro package of the week is iraf-wcstools. WCSTools is a set of software utilities, written in C, which create, display and manipulate the world coordinate system of a FITS or IRAF image, using specific keywords in the image header which relate pixel position within the image to position on the sky. Auxiliary programs search star catalogs and manipulate images.

This package contains the IRAF package.

Random #Debian Astro package of the week is iraf-mscred. The MSCRED external package is used to reduce CCD mosaic data in multiextension FITS format. This format is produced for example by the Data Capture Agent when observing with the NOAO CCD Mosaic Imager, as well as similar instruments from AAO, CFA, CFHT, ESO, INT and others.

The tasks in the mscred package perform the following functions:

* display the mosaic data as an apparent

Good news everyone!

October Astro soft update is out there for review in Guix.

This month brought us the latest @astropy, Stellarium and @Siril_Official.

IRAF Community, maintained
by @olebole, is packed and will be available after it's reviewed and merged.

Random #Debian Astro package of the week is iraf-rvsao. This package obtains radial velocities and velocity dispersions using cross-correlation methods or emission line fits. It consists of several SPP tasks:

* XCSAO and PXCSAO: cross-correlate spectra,
* EMSAO and PEMSAO: find emission lines in spectra,
* BCVCORR: solar system barycentric velocity correction,
* SUMSPEC: add and/or modify spectra,
* LINESPEC: synthetic emission line
