Mass accretion rates derived in this work against those derived by Garcia Lopez et al. (2006) (filled symbols) and Donehew & Brittain (2011) (open symbols). The dashed line indicates equal values and the dotted lines  ± 1 dex. The typical minimum uncertainty for the estimates in Garcia Lopez et al. (2006) is  ± 0.5 dex. Triangles are upper limits. Grey symbols represent the estimates using the method in Garcia Lopez et al. (2006) from our distances and stellar parameters, and the solid line is the best fit.
