The RMS Survey. H2O masers towards a sample of southern hemisphere massive YSO candidates and ultra compact HII regions. Urquhart J.S., Hoare M.G., Lumsden S.L., Oudmaijer R.D., Moore T.J.T., Brook P.R., Mottram J.C., Davies B., Stead J.J. <Astron. Astrophys. 507, 795 (2009)> =2009A&A...507..795U

To search for H2O masers towards a large sample of young high mass stars and to investigate the statistical correlation of H2O masers with the earliest stages of massive star formation. We have used the Mopra Radio telescope to make position-switched observations towards ∼500 UCHII regions and MYSOs candidates identified from the RMS survey and located between 190°<l<30°. These observations have a 4σ sensitivity of ∼1Jy and a velocity resolution of ∼0.4km/s. Description: Results of a set of water maser observations towards an MSX and 2MASS colour selected sample of massive young stellar object candidates. Table 1: Field names, positions, observational rms values; Table 2: detected water maser sources their parameters and classification of associated MSX point sources. File Summary:
