Abstract:
The Red MSX Source (RMS) survey is returning a large sample of massive
young stellar objects (MYSOs) and ultra-compact (UC) HII regions using
follow-up observations of colour-selected candidates from the MSX
point source catalogue.
To obtain the bolometric fluxes and, using kinematic distance
information, the luminosities for young RMS sources with far-infrared
fluxes.
Description:
We use a model spectral energy distribution (SED) fitter to obtain the
bolometric flux for our sources, given flux data from our work and the
literature. The inputs to the model fitter were optimised by a series
of investigations designed to reveal the effect varying these inputs
had on the resulting bolometric flux. Kinematic distances derived from
molecular line observations were then used to calculate the luminosity
of each source.

Global Notes:
Note (G1): RMS classification contains the following basic types,
discussed in Mottram et al. (2010A&A...510A..89M 2010A&A...510A..89M):
HII = HII regions
YSO = Young Stellar Objects
DHII = Compact HII regions
Y/O Str = Young / Old star, unlikely to be H ii regions or PNe
HII/YSO = both indications of HII region and Young Stellar Object
