The red MSX source survey: the massive young stellar population of our Galaxy. Lumsden S.L., Hoare M.G., Urquhart J.S., Oudmaijer R.D., Davies B., Mottram J.C., Cooper H.D.B., Moore T.J.T. <Astrophys. J. Suppl. Ser., 208, 11 (2013)> =2013ApJS..208...11L

We outline the construction of the catalog using mid- and near-infrared color selection. We also discuss the detailed follow up work at other wavelengths, including higher spatial resolution data in the infrared. We show that within the adopted selection bounds we are more than 90% complete for the massive protostellar population, with a positional accuracy of the exciting source of better than 2 arcsec. We briefly summarize some of the results that can be obtained from studying the properties of the objects in the catalog as a whole; we find evidence that the most massive stars form: (1) preferentially nearer the Galactic center than the anti-center; (2) in the most heavily reddened environments, suggestive of high accretion rates; and (3) from the most massive cloud cores. Description: The Midcourse Space Experiment (MSX) satellite mission included an astronomy experiment (SPIRIT III) designed to acquire mid-infrared photometry of sources in the Galactic plane (b<5°). MSX had a raw resolution of 18.3", a beam size 50 times smaller than that of IRAS at 12 and 25um. MSX observed six bands between 4 and 21um, of which the four between 8 and 21um are sensitive to astronomical sources. We used v2.3 of the MSX PSC (Egan et al. 2003, Cat. V/114) as our basic input, restricting ourselves to the main Galactic plane catalog, which excludes sources seen in only a single observing pass and those seen in multiple passes but with low significance. We restricted our catalog to 10<l<350° in order to avoid problems with greater source confusion, as well as kinematic distance ambiguities near the Galactic center. File Summary:

Note (1): With kinematic distance ambiguity. Note (2): If the adopted distance is different from kinematic near and far distances, it indicates a non-kinematic origin for the distance such as parallax. Note (3): the types are: * Stars: Carbon star; Evolved star; OH/IR star; Young/old star; YSO * Non-stars: PN; Proto-PN; HII region; HII/YSO; Other Note (4): the color cuts boundaries are: F21>2F8 , F21>F14 , F14>F8 , F8>5FK and FK>2FJ. The sources failing the color cuts with J and K are marked in the column "fcc"-------------------------------------------------------------------------------- Byte-by-byte Description of file: table2.dat

Note (1): These names are only given for sources with more than 10 citations on SIMBAD for counterparts within 20 arcsec of the central RMS source. We present all the objects we classify purely as YSOs, as well as those that have clear characteristics of HII regions (e.g., strong radio emission), but where the central exciting star still retains characteristics of a YSO, such as spectral evidence for a disk (see, e.g., Cooper et al. 2013MNRAS.430.1125C). Only about half of our most luminous protostars are sufficiently well studied to have a common "Other Name."-------------------------------------------------------------------------------- History:
