Comparisons between the total disc fluxes measured from the new continuum observation with that measured from the data presented by Manara et al. (2019). The left panel shows the ratio between the total fluxes calculated using the data by Manara et al. (2019) (F_{Manara,c.f.t.}) and using the new continuum data (F_new), both estimated through the cumulative flux technique. The right-hand panel instead reports the ratio using the fluxes calculated by Manara et al. (2019) with the uv-modelling method (F_{Manara,Galario}), and using the new continuum data with the cumulative flux technique. Red circles are used for circumprimary discs, blue squares for circumsecondary ones.
