Measurements of emission-line fluxes for Br-gamma and H2 1-0 S(1) are presented for 30, mostly low-luminosity, young stellar objects. The strong hydrogen recombination lines in the low-luminosity objects are more difficult to explain than those in high-luminosity young stellar objects. A spectrum of the high-order Pfund emission lines (Pf 20-25) in S106-IRS3 is presented which indicates high optical depths in the Pfund lines in this source. 30 refs.
