Astrophysics Source Code Library

The Astrophysics Source Code Library (ASCL) is a free online registry and repository for source codes of interest to astronomers and astrophysicists, including solar system astronomers, and lists codes that have been used in research that has appeared in, or been submitted to, peer-reviewed publications. The ASCL is indexed by the SAO/NASA Astrophysics Data System (ADS) and Web of Science and is citable by using the unique ascl ID assigned to each code.

[ascl:2508.019] FiCUS: FItting the stellar Continuum of Uv SpectraSaldana-Lopez, A.; Schaerer, D.; Chisholm, J.; Calabrò, A.; Pentericci, L.; Cullen, F.; Saxena, A.; Amorín, R.; Carnall, A. C.; Fontanot, F.; Fynbo, J. P. U.; Guaita, L.; Hathi, N. P.; Hibon, P.; Ji, Z.; McLeod, D. J.; Pompei, E.; Zamorani, G. The code takes observed-frame wavelength, flux density (with errors) and user-defined mask arrays as inputs, and returns an estimation of the galaxy stellar age, metallicity and dust extinction, as well as other secondary Spectral Energy Distribution (SED) parameters.
