Time evolution of the mass accretion rate across all observations seen in Hα (blue circles) and Paschen γ (orange squares). Black diamonds show the average over the following available tracers at each epoch: Paschen δ, Paschen β, Brackett γ, and Hα, each shown with small light gray circles. A small offset in date has been applied for clarity. The Paγ and Hα accretion rate error bars represent the uncertainties from the line flux measurements only. Systematic uncertainties in the accretion rate, primarily from the adopted L_line–L_acc relation and stellar parameters, are not shown; these amount to ∼0.4 dex.
