Ṁ_acc,c versus flux of the CaII λ866.2 line. The blue triangles and the blue lines (long- and short-dashed) represent the data set and the correlation found by Mohanty et al. (2005). The black asterisk are the sample taken into account by HH08 and the blue dotted-dashed lines are the relationships found in their paper. The red points are the objects analyzed in this paper. The green solid line is the least square fit of all the targets plotted in the figure, neglecting the upper limits.
