[ascl:2312.033] RADIS: Fast line-by-line code for high-resolution infrared molecular spectra
Pannier, E.; Laux, C.O.; van den Bekerom, D.C.M.; Minesi, N.; Soref, J.; Kumar, A.; Misra, P.; Verma, S.; Grimaldi, C.; Sharma, S.; Huy, T.H.N.; Aryan, G.; Kawahara, H.

RADIS resolves spectra with millions of lines within seconds on a single-CPU and can be GPU-accelerated. It supports HITRAN, HITEMP and ExoMol out-of-the-box (auto-download), and therefore is particularly suitable to compute cross-sections or transmission spectra at high-temperature. RADIS includes equilibrium calculations for all species, and non-LTE for CO2 and CO.

[ascl:2504.032] DMCalc: In-band dispersion measure of pulsars calculator
Krishnakumar, M. A.; Manoharan, P. K.; Joshi, B. C.; Girgaonkar, R.; Desai, S.; Bagchi, M.; Nobleson, K.; Dey, L.; Susobhanan, A.; Susarla, S. C.; Surnis, M. P.; Maan, Y.; Gopakumar, A.; Basu, A.; Batra, N. D.; Choudhary, A.; De, K.; Gupta, Y.; Naidu, A. K.; Pathak, D.; Singha, J.; Prabu, T.

DMCalc estimates the Dispersion Measure (DM) of wide-band pulsar data in psrfits format. It uses PSRCHIVE (ascl:1105.014) tools to get ToAs and then uses TEMPO2 (ascl:1210.015) for DM fitting. A median absolute deviation (MAD) based ToA rejection algorithm is implemented in the code to remove large outlier ToAs using Huber Regression. Although the code has been used for analyzing uGMRT wide-band data, DMCalc can in principle be used for any pulsar dataset.
