Accretion luminosities vs. spectral type as obtained using FRAPPE (gray squares) and obtained using the method of Manara et al. (2013b) (red triangles). 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 circles are the nearly complete Chamaeleon I sample presented by Manara et al. (2013a). The black errorbars indicate the uncertainties on the accretion luminosity. The gray arrows indicate sources listed as upper limits by Manara et al. (2023).
