Comparison of the integrated mass loss rates as a function of the X-ray luminosity (left panel) and the surface mass loss profiles as a function of disc radius (centre and right panel) for the photoevaporation profiles by Owen et al. (2012) and Picogna et al. (2019). For the plots showing it is assumed that photoevaporation already opened a gap in the disc, which has moved up to 10 au, while theinner disc was drained. At this point, the inner edge of the outer disc is located at 10 au, and the column density of the inner disc is less than 2.5 × 10²² cm⁻². Inside of 10 au the primordial profile is active (Eqs. (A.2) and (A.8), respectively), and outside of 10 au the transition disc profile (Eqs. (A.5) and (A.10), respectively). The solid lines show the total mass loss profile, while the dotted lines only highlight the primordial profile for each case (i.e. assuming photoevaporation had not opened a gap and the disc is still in its primordial stage).
