cds-question@unistra.fryoung-stellar-objectspre-main-sequence-starsradio-astronomyThe Red MSX Source (RMS) survey is an ongoing multi-wavelength observational programme designed to return a large, well-selected sample of massive young stellar objects (MYSOs). We have identified ~2000 MYSOs candidates located within our Galaxy by comparing the colours of MSX and 2MASS point sources to those of known MYSOs. The aim of our follow-up observations is to identify other contaminating objects such as ultra compact (UC) HII regions, evolved stars and planetary nebulae (PNe) and distinguish between genuine MYSOs and nearby low-mass YSOs. A critical part of our follow-up programme is to conduct ^13^CO molecular line observations in order to determine kinematic distances to all of our MYSO candidates. These distances will be used in combination with far-IR and (sub)millimetre fluxes to determine bolometric luminosities which will allow us to identify and remove nearby low-mass YSOs. In addition these molecular line observations will help in identifying evolved stars which are weak CO emitters. We have used the 22m Mopra telescope, the 15m JCMT and the 20m Onsala telescope to conduct molecular line observations towards 854 MYSOs candidates located in the 3rd and 4th quadrants. These observations have been made at the J=1-0 (Mopra and Onsala) and J=2-1 (JCMT) rotational transition frequency of ^13^CO molecules and have a spatial resolution of ~20"-40", a sensitivity of T_A_^*^~0.1K and a velocity resolution of ~0.2km/s.2007A&A...474..891Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/474/891CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/461/11 : Radio observations of MYSO candidates (Urquhart+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/474/891https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/474/891http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/474/891https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/474/891https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/474/891http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/474/891GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/474/891/table3 (*Summary of the RMS sources observed, observed positions, the rms noise levels of the reduced spectra, line component parameters and Galactic kinematic distances.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/474/891/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/474/891/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/474/891/table3?GETtext/xml+votable180.050000true86.714325.06280.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/474/8914/2652 5/9474 9480 10419-10420 10441 10444 10453 10539 10542 10553 10556 10594-10595 10597-10598 10624 6/20831 21504 21523 21542 21637 21639 21641 21643 21646-21647 21670-21671 21689 22038 22040 22045 22065 22070 22075 22078 22113 22115 22122 22124 22161 22208 22212 22243 23636-23637 23639 23646 23664 23666 23764 23766 23773 23949 23968-23969 23982-23983 24189 24325 24355-24356 24361 24371 37333 37335 37339 37341-37343 37362 37364 37366-37369 37372-37373 37713 37718 37720 37732 37734 37745-37746 37749 37829 37831 37839 37842 37849-37850 37855 37860-37861 37870 37872 37878 37882 37884 37886-37887 37890 37893-37895 37900 37902-37904 37906 37913 37924 37928-37929 37931 37934 38016 38018-38019 38026-38027 38435 38538 38563 39240 39246 39248 39250 39252 39259 39268 39273 39276 39280 39282 39375 39404 39745 39774 39803 39891 39895 39899 39926 39935 40612 40618-40619 41466 41470-41471 41581 41586 41594-41597 41599 41631 41646-41647 41653-41658 41660 41663 41670-41671 41673 41675 41684 41687-41689 41691 41693-41694 41696 41698 41701-41702 41740 41751 41756 41758-41760 41763 41769-41770 41772 41774 41780-41782 41786 41788 41793 41798-41800 41802-41806 41809 41811 41816-41817 41819-41820 41822 41824-41825 41827 41832 41857 41866 41920 42152 42155 42160 42163-42164 42167 42172-42174 42190-42191 42202 42206-42207 42209-42211 42216-42217 42219-42220 42228-42230 42232-42233 42286 42302 42345 42347 42349-42350 42362 42371-42372 42387 42396-42398 42400 42403 42417 42421 42464 42466 42478 42500-42502 42504-42505 42512 42514-42516 42518-42519 42529 42560-42561 42757 43009-43011 43014 43019-43021 43024 43026 43040-43041 43047https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/474/891?format=asciiRadiodefaultJ/A+A/474/891/table3*Summary of the RMS sources observed, observed positions, the rms noise levels of the reduced spectra, line component parameters and Galactic kinematic distances.recnoRecord number assigned by the VizieR team.
