This directory contains two-dimensional maps of the mass-to-light ratio (M/L)
for all galaxies in the Atlas3D sample (Cappellari et al., 2011). The M/L
values are fit for in pPXF (Cappellari & Emsellem, 2004). Each observed
spectrum (binned to a minimum S/N) from the SAURON IFU is fit to the Single
Stellar Population (SSP) template library of Vazdekis et al. (2012), which vary
in age and stellar metallicity, assuming a constant Salpeter Initial Mass
Function (IMF). This process, and the application of these maps, are described
in detail in Poci et al. (2017) and references therein.
