Notes. The first column is the protostellar mass, followed by its age and luminosity. Tbol is the bolometric temperature as defined by Myers & Ladd (1993). M10 000 AU is the gas mass within a radius of 10 000 AU from the protostar. Finally, n0 and p are the fitted parameters for the power law, ρ(r) = n0(r/ 100 AU)p.
