Comparison of stellar mass estimators. Panel a: compares the CIGALE estimates of M_⋆, using two stellar populations (x-axis), with the Eskew et al. (2012, y-axis) empirical approximation, both assuming a Salpeter (1955) IMF. Panel b: compares the same x-axis as panel a to the CIGALE estimates, using a single stellar population and a Chabrier (2003) IMF, by N20. In both panels, the blue symbols correspond to the values presented in Nersesian et al. (2019), and the red symbols correspond to the values estimated for this study, with the same CIGALE settings. The solid yellow line represents the 1:1 relation. The dashed yellow line in panel b represents the 1:0.61 relation that accounts for the difference in IMFs.
