Evolution of the disk observables, for different FUV fields and trap locations (1 /3r_c, 2/3r_c or none). Top: evolution disk flux in the 1.3 mm continuum at a distance of 400 pc. Bottom: time evolution of the r_90% enclosing 90% (black) of the disk emission in the continuum above the sensitivity limit (0.1 mJy beam^-1), and the photoevaporative radius derived from the FRIED grid mass loss profile (red dotted lines, see Sellek et al. 2020). We note that towards the end of the simulation the calculation of the photoevaporative radius suffers from numerical effects due to the discrete nature of the FRIED grid.
