Mass accretion rate as a function of mass for the ρ-Oph sample. Values derived for the objects analyzed here are reported with black markers, values from N06 are shown with red symbols. Empty black circles are used for subluminous targets and downward arrows are used for upper limits. The continuous line represents the linear fit of this relation by Alcalá et al. (2014) for a sample of accreting objects in Lupus. The dashed lines represent the 1σ deviation from the fit.
