ZAMS spectral type estimates from IR data vs. those from radio data for the five observed cores. Estimates using the flux apportionment method described in the text are shown with filled symbols. Estimates assuming a single source produces all the flux are shown with open symbols. The solid line is a linear fit to the spectral types from our apportionment method; the dotted line shows the locus where the radio and IR ZAMS spectral types are equal. Error bars are ±0.5 spectral classes.
