Description
The MaNGA Firefly Value-Added-Catalogue (VAC) provides measurements of spatially resolved stellar population properties in MaNGA galaxies. It is built upon the MaNGA data analysis pipeline (DAP) and employs the full spectral fitting code FIREFLY to derive parameters such as stellar ages, metallicities, masses, star formation histories and dust attenuation. In addition to Voronoi-binned measurements, it also provides global properties, such as central values and radial gradients. With this poster, I will give an update on the MaNGA Firefly VAC that now doubled in sample size (~10,000 galaxies) as compared to the version published in SDSS DR15. One of the major new additions is the choice to select the results from fits that used either the MILES or the novel MaStar models, the later of which allow to constrain the fit over the whole MaNGA wavelength range.
