Mass accretion rate vs. stellar mass as obtained using FRAPPE (red triangles) and obtained using the method of Manara et al. (2013b) (gray squares). Results obtained for the same target with the two methods are connected with a blue line. The green triangle indicates the M5 solution of WZ Cha. The light blue dots are the nearly complete Chamaeleon I sample presented by Manara et al. (2013a). The blue errorbars indicate the uncertainties on the stellar mass and mass accretion rate. The gray arrows indicate sources listed as upper limits by Manara et al. (2023).
