and saves the result in FITS format.

This metapackage depends on all the Gyoto interfaces (command-line, Python 3 and Yorick).

MPI parallelization requires the mpi-default-bin package. The Gyoto documentation is provided in the gyoto-doc package.

Gyoto: Gyoto

#datasimulation #AstronomySoftware #ScienceSoftware

Random #Debian Astro package of the week is gyoto. Gyoto is a framework for computing geodesics in curved space-times. The gyoto utility program uses this framework to compute images of astronomical objects in the vicinity of compact objects (e.g. black-holes). Such images are distorted by strong gravitational lensing. The gyoto program takes a scenery description in XML format, computes this scenery using relativistic ray-tracing,

#IRAF #AstronomySoftware #ScienceSoftware

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.

WCSTools: Image World Coordinate System Utilities

#IRAF #AstronomySoftware #ScienceSoftware

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.

After two and a half years of building this community, I've made the decision that it's time to shut down Astrodon.social.

Since 2022, around 4,000 users have registered on astrodon.social. However, fewer than 10% of those users are active each month, and fewer than 1% post regularly. Because of the way Mastodon works, the data for every one of the those users, even the inactive ones, has to be kept forever and keeps on growing. There's no way to remove posts or archive them out of the database, and running a large database gets very expensive.

Running Astrodon costs more than €300/month, which means that the costs of running the server are primarily going toward servicing fewer than 50 active users, the most active of whom are organisations. Even with donations, Astrodon has now cost me more than €5000 to run.

While I’ve considered the option of turning Astrodon into a commercial service or creating a nonprofit, I’m reluctant to go down that route. Managing a business comes with a host of overhead tasks like tax reporting and navigating different tax regimes due to our global user base, which is something I want to avoid. My goal has always been to create a free and open space, but the reality is that the free part isn't sustainable.

I'm not shutting down Astrodon immediately. I want to give everyone ample time—likely over the next two to three months—to find alternative service providers and transition smoothly. This isn't a decision I'm making lightly, and I appreciate your understanding and support as we navigate this transition. If you have any questions, concerns, or suggestions, please feel free to reach out to me directly through DMs.

* Display the tracking data in lists, maps, polar plots and any combination
of these
* Have many modules open at the same either in a notebook or in their own
windows. The modules can also run in full-screen mode
* You can use many ground stations
* Predict upcoming passes
* Gpredict can run in real-time, simulated real-time (fast forward and
backward), and manual time control
* Detailed information both the real time and non-real time modes

#DebianEdu #AstronomySoftware #ScienceSoftware

Random #Debian Astro package of the week is gpredict. Gpredict is a real time satellite tracking and orbit prediction program for the Linux desktop. It uses the SGP4/SDP4 propagation algorithms together with NORAD two-line element sets (TLE).

Some core features of Gpredict include:

* Tracking of a large number of satellites only limited by the physical
memory and processing power of the computer

* Doppler tuning of radios via Hamlib rigctld
* Antenna rotator control via Hamlib rotctld
