Lacc values derived from Brγ and Paβ for Lupus (purple diamonds) and Serpens (cyan circles) sources plotted as a function of L∗. Downward triangles indicate upper limits on Lacc. The solid and dashed lines show the locus where Lacc = L∗ and Lacc = 0.1L∗. The mean uncertainty on the single points is also shown.
