Mass accretion rate Ṁ_acc as a function of M_⋆ in log  scale as determined using the four different PMS evolutionary models described in Section A. The YSOs with transitional discs are distinguished with crossed squares, while the sub-luminous objects are shown with open circles. The low accretors are shown with red symbols (see Sect. B.1). The arrows show upper or lower limits on the mass according to the availability of the tracks in each model. Average errors are shown in the upper left of each panel. The purple dashed lines represent the corresponding linear fits as in Table A.1.
