Ṁ_acc values obtained with the two methods described in the text. Ṁ_acc values on the y-axis are inferred from ugr snapshot photometry, while Ṁ_acc values on the x-axis correspond to the median UV excess detected during the ur monitoring. Colors and sizes of symbols are scaled according to stellar mass M_∗. The solid line marks the equality line; the linear regression to the point distribution is traced as a dashed line.
