The MaNGA FIREFLY Value-Added-Catalogue: resolved stellar populations of
  10,010 nearby galaxies
  We present the MaNGA FIREFLY Value-Added-Catalogue (VAC) - a catalogue of
~3.7 million spatially resolved stellar population properties across 10,010
nearby galaxies from the final data release of the MaNGA survey. The full
spectral fitting code firefly is employed to derive parameters such as stellar
ages, metallicities, stellar and remnant masses, star formation histories, star
formation rates and dust attenuation. In addition to Voronoi-binned
measurements, our VAC also provides global properties, such as central values
and radial gradients. Two variants of the VAC are available: presenting the
results from fits using the M11-MILES and the novel MaStar stellar population
models. MaStar allows to constrain the fit over the whole MaNGA wavelength
range, extends the age-metallicity parameter space, and uses empirical spectra
from the same instrument as MaNGA. The fits employing MaStar models find on
average slightly younger ages, higher mass-weighted metallicities and smaller
colour excesses. These differences are reduced when matching wavelength range
and converging template grids. We further report that FIREFLY stellar masses
are systematically lower by ~0.3 dex than masses from the MaNGA PCA and Pipe3D
VACs, but match masses from the NSA best with only ~0.1 dex difference.
Finally, we show that FIREFLY stellar ages correlate with spectral index age
indicators H$\delta_A$ and $D_n$(4000), though with a clear additional
metallicity dependence.
