4th release of RADIS in 2021, and the largest so far !
New physics with ExoMol support, by-default truncations to account for subLorentzian behaviors, custom abundances for non-terrestrial atmospheres. Major improvements in performances (reduced memory consumption, faster database loading, up to 10x faster small CPU spectra, large range spectra are 2-30x faster, 3500x faster nonequilibrium partition functions). A few handy features for post-processing (custom plotting themes, ruler tool) or for the calculations (automatic wavenumber grid, fitting methods, new profiler, new choice of truncation & effect of neighbour lines), and even a new method to automatically cite the papers that contributed to your calculation ! 🏃
Also notice that the HITRAN team has completed major additions to the database (see "Database Update" on the the HITRAN website), and these are available in RADIS with databank='hitran'
Automatic wstep attribution in calc_spectrum() #250 Automatic wavenumber grid resolution by @anandxkumar : makes sure you always have the right balance in between accuracy and performance. Will become the default mode in 0.9.31, try it before by setting wstep='auto' in calc_spectrum or SpectrumFactory . Feedback welcome !
Note : some performance improvements are not activated by default in this version. See partfunc="tabulation"#316 , wstep='auto'#250 , or fetch_hitemp("OH", engine="vaex")#306 . Try them !
RADIS-Lab was updated with preconfigured HITEMP-H2O lines. Try it out, or share it : no install needed (will be updated in the coming days with RADIS 0.9.30 support).
@dcmvdbekerom gave a talk describing the DIT algorithm that powers RADIS. The 15-min video is available here.
an automatically differentiated version of the DIT algorithm has been implemented in the Exojax code by @HajimeKawahara, to model exoplanets, brown drafts and generally for inverse problems in radiative transfer. Have a look !

And also, lot's of new Examples of what can be done with RADIS :
10 people contributed to this version, including the major works of @anandxkumar and @gagan-aryan on their OpenAstronomy GSOC-2021 projects. 👏
