Reasons To Register Your Software With The Astrophysics Source Code Library
This presentation covered the benefits of registering astronomy research software with the Astrophysics Source Code Library (ASCL, https://ascl.net/ ), a free online registry for software used in astronomy research.
![Focal planes produced by ExoSim 2 for the Ariel VISPhot channel using two different PSFs. The focal plane array size is 64 × 64 pixels, oversampled by a factor of 3. Both panels are presented in decibels ([dB]) units to highlight the PSF side lobes. The left panel shows the effective PSF using an Airy function, which is cropped to the 8th zero. The right panel presents the effective PSF using a PAOS-simulated PSF as input, including aberrations and a defocusing of 200 nm root mean square (RMS) on the wavefront. -- astro-ph.IM](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/01/ExoSim-2-The-New-Exoplanet.png?resize=1200%2C721&ssl=1)
