Comparison of the absolute masses and the masses derived from the MTGR. Error bars in the y axis are the uncertainties of the absolute masses given in Eker et al. (2018). Error bars in the x axis are the propagated uncertainties for MTGR masses caused by the uncertainties in T_eff and log g of the samples (see Sect. 6). For the regression line, the points are weighted according to their measurement errors.
