Disc mass distribution at 0.5 Myr and 2.5 Myr for the viscousphotoevaporative model (solid line), compared with purely viscous distributions (dashed line). The dotted vertical lines indicate the medians of the distributions of survived discs, while the hatched regions correspond to dispersed discs. This population has $\langle \log \left(M_0/{\text{M}}_{\odot }\right)\rangle =-2.5,\langle \log \left({\dot{M}}_0/{\text{M}}_{\odot }{\text{yr}}^{-1}\right)\rangle =-8.3$, and $\langle \log \left({\dot{M}}_{\text{w}}/{\text{M}}_{\odot }{\text{yr}}^{-1}\right)\rangle =-9.6$, where all quantities follow log-normal distributions with σ = 0.5 dex.
