Sky simulation output format #1

Closed sfiruch closed 2 years ago

sfiruch commented 3 years ago

What is the interface between the Sky simulation and the Telescope module? What file format/API should we use initially? What are the pros/cons of the already existing formats?

rohitcbscient commented 3 years ago

The interface between sky simulation and telescope module are 2-D images. The most common format is the FITS format for the astrophysical images. We can maybe start with Fits format. The major pro is that it can be an easy interface for the other astronomical software, i.e. user-friendly. The con could be large data sizes, reading and writing rates? Visualisation of fits images would be a challenge too if the sources structures are complex.

Can you point to a couple example files, to get an impression of the headers?

rohitcbscient commented 3 years ago

Yes, the most ideal example would be to look at the all-sky radio maps. Here is the link to download fits files: https://lambda.gsfc.nasa.gov/product/foreground/fg_2014_haslam_408_get.cfm We can use these files for the sky module to simulate the sky.

Lucio Meyer (UniZH) can provide more information about their simulation. No meeting set yet.
