Ṁ_acc medians and percentiles as a function of age for L1688 (red), Lupus (blue), Chamaeleon I (yellow), and Upper Scorpius (green). From top to bottom: for the full range of stellar masses 0.15 ≤ Μ_⋆/Μ_⊙ < 3.0 (after removing the trends with M_⋆ as derived in Appendix H), and for three mass bins, as labeled. In each case, the dotted line shows the trend Ṁ_acc ∝ t⁻¹, normalized to the median value for L1688. The filled box shows the possible range of the median value, following the treatment of upper limits described in the text.
