Comparison between mass-loss rates scaled values from the literature (Ṁ_lit) and Ṁ obtained in this work fitted with R_s = R_CO/2.5. The solid line indicates equality, the dashed lines relationships 1/2 and 2, and the dotted lines relationships 1/3 and 3. Filled circles and empty squares indicate previous studies with radiative transfer models and with empirical laws, respectively.
