Mass accretion rate based on the accretion luminosity as a function of the mass accretion rate based on ℱ and f, for the 2010 and 2012 data. The gray dotted line shows a one-to-one relationship. The uncertainty on the x-axis is shown on the lower left (see text for details). We note that the accretion shock model method finds almost systematically higher accretion rates than does the accretion luminosity method.
