Good news everyone!
October Astro soft update is out there for review in Guix.
This month brought us the latest @astropy, Stellarium and @Siril_Official.
IRAF Community, maintained
by @olebole, is packed and will be available after it's reviewed and merged.

Whoa.
`nifty-ls` claims to be a faster, more accurate drop-in replacement for #astropy's Lomb-Scargle periodogram.
I've briefly experimented with the Kepler short cadence light curve for the enigmatic δ Sct variable HD 187547 (~1M data points) and `nifty-ls` really is ~5-8× faster than the usual `fast` method, for the price of one minimal-dependency import and one keyword argument. 🚀
Plus the authors show it's more accurate, too! 🎯
We present nifty-ls, a software package for fast and accurate evaluation of the Lomb-Scargle periodogram. nifty-ls leverages the fact that Lomb-Scargle can be computed using a non-uniform FFT (NUFFT), which we evaluate with the Flatiron Institute NUFFT package (finufft). This approach achieves a many-fold speedup over the Press & Rybicki (1989) method as implemented in Astropy and is simultaneously many orders of magnitude more accurate. nifty-ls also supports fast evaluation on GPUs via CUDA and integrates with the Astropy Lomb-Scargle interface. nifty-ls is publicly available as open-source software.
Patch series is ready for review for Guix team bringing fresh astro soft 2024/07.
