\caption{\label{tab:shiftsmass}Different setups for different mass-metallicity relations found in
the literature, and associated shifts to be applied to their stellar
masses in order for them to be comparable with our results. This table
shows the type of data, the models, the presence or not of secondary
bursts, and the IMF used to compute the stellar masses. The last column
gives the global shift that has to be applied to the logarithm of
the stellar mass.}
