Automatic generation of graph drawings has important applications in key technologies such as database design, software engineering, VLSI and network design and visual interfaces in other domains. Situations where these tools might be particularly useful include:.2/5⤵.

#SciencePublication #AstronomySoftware #ScienceSoftware.Random #Debian Astro package of the week is graphviz. Graph drawing addresses the problem of visualizing structural information by constructing geometric representations of abstract graphs and networks. 1/5⤵

These packages are expressing an interest in Astropy’s goals of improving reuse, interoperability, and interface standards for Python astronomy and astrophysics packages. This metapackage installs all affiliated packages that are packaged for Debian. 3/3.

An affiliated package is an astronomy-related Python package that is not part of the astropy core package, but has requested to be included as part of the Astropy project’s community. 2/3⤵.

#AstroPython #AstronomySoftware #ScienceSoftware. Random #Debian Astro package of the week is python3-astropy-affiliated. A major part of the Astropy project is the concept of “Affiliated Packages”. 1/3⤵.

These generally fail for stellar astronomical images, since stars have very little stable structure and so, in general, indistinguishable from each other. Asterism matching is more robust, and closer to the human way of matching stellar images. 3/3.

It does so by finding similar 3-point asterisms (triangles) in both images and deducing the affine transformation between them. Generic registration routines try to match feature points, using corner detection routines to make the point correspondence. 2/3⤵.

#AstroPython #AstronomySoftware #ScienceSoftware. Random #Debian Astro package of the week is python3-astroalign. Astroalign is a Python module that will try to align two stellar astronomical images, especially when there is no WCS information available. 1/3⤵.

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 IRAF system and all applications are written. 2/3⤵.

#IRAF #AstronomySoftware #ScienceSoftware. 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. 1/3⤵.

#telescopecontrol #AstronomySoftware #ScienceSoftware. Random #Debian Astro package of the week is aravis-tools. Basic viewer for aravis compatible cameras, real-time camera control using GenICam implemented properties (arv-viewer-0.8).

This package installs the library for Python 3. 2/2.

#AstroPython #AstronomySoftware #ScienceSoftware. Random #Debian Astro package of the week is python3-pygnuplot. PyGnuplot works as a Python pipe for Gnuplot allowing to pipe commands to Gnuplot command prompt, plot, save data files, create postscript and PDF files. 1/2⤵.

coordinate conversions, and manipulating FITS images with World Coordinate System (WCS) information through PyWCSTools - a simple wrapping of WCSTools by Jessica Mink. PyWCSTools is distributed (and developed) as part of astLib. 2/2.

#AstroPython #AstronomySoftware #ScienceSoftware. Random #Debian Astro package of the week is python3-astlib. astLib is a set of Python3 modules that provides some tools for research astronomers. It can be used for astronomical plots, some statistics, common calculations,. 1/2⤵.
