cds-question@unistra.frastrophysical-masersradio-astronomyh-ii-regionsradio-continuum-emissionradial-velocityWe conducted Very Large Array C-configuration observations to measure positions and luminosities of Galactic Class II 6.7GHz methanol masers and their associated ultra-compact HII regions. The spectral resolution was 3.90625kHz and the continuum sensitivity reached 45{mu}Jy/beam. We mapped 372 methanol masers with peak flux densities of more than 2Jy selected from the literature. Absolute positions have nominal uncertainties of 0.3". In this first paper on the data analysis, we present three catalogs; the first gives information on the strongest feature of 367 methanol maser sources, and the second provides information on all detected maser spots. The third catalog presents derived data of the 127 radio continuum counterparts associated with maser sources. Our detection rate of radio continuum counterparts toward methanol masers is approximately one-third. Our catalogs list properties including distance, flux density, luminosity, and the distribution in the Galactic plane. We found no significant relationship between luminosities of masers and their associated radio continuum counterparts, however, the detection rate of radio continuum emission toward maser sources increases statistically with the maser luminosities.2016ApJ...833...18Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/833/18CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/96 : 6-GHz methanol multibeam maser catalogue (Caswell+, 2010-12)J/MNRAS/446/3461 : 6.7-GHz methanol masers-dust associations (Urquhart+, 2015)J/ApJ/783/130 : Parallaxes of high mass star forming regions (Reid+, 2014)J/A+A/563/A130 : GLIMPSE/BGPS 6.7GHz methanol maser survey (Sun+, 2014)J/other/IJAA/4.571 : Methanol masers in HII regions (Farmer, 2014)J/MNRAS/435/400 : ATLASGAL.
