The STELLar ABundances (STELLAB) module consists of a collection of data that can be manipulated to visualize any chemical abundance ratio observed in stars for a wide range of metallicities. The database is continuously updated and include several datasets for the Milky Way and local dwarf galaxies (Carina, Sculptor, Fornax, and the Large Magellanic Cloud). STELLAB and OMEGA, our galaxy model, can be used together to compare chemical evolution predictions, which originate from the stellar models used by SYGMA, with real observations. For more information on how to use STELLAB and for a list of available galaxies and datasets, we refer to the GettingStarted and Documentation tabs.
