SED of a probable protostellar core in the Monoceros R2 region. Blue crosses represent reliable data points; red crosses represent short-wavelength data points used only for luminosity calculations (while not present here, some SEDs within the catalogue also show red crosses, albeit with long error-bars, which represent unreliable data points, which are used for SED fitting, but with greatly increased errors). The χ² value of the fit is given at the upper left of the plot. The snapshots of this source are given in Fig. D.1. We note that the fluxes are those used for the SED calculation, and have thus been modified using flux scaling.
