ULySS (University of Lyon Spectroscopic analysis Software) is an open-source software package written in the GDL/IDL language to analyse astronomical data.
ULySS fits a spectrum with a linear combination of non-linear components convolved with a line-of-sight velocity distribution (LOSVD) and multiplied by a polynomial continuum.
ULySS is used to study stellar populations of galaxies and star clusters and atmospheric parameters of stars.
