On the Relationship of UC H II Regions and Class II Methanol Masers: I.
  Source Catalogs
  We conducted VLA C-configuration observations to measure positions and
luminosities of Galactic Class II 6.7 GHz methanol masers and their associated
ultra-compact H II regions. The spectral resolution was 3.90625 kHz and the
continuum sensitivity reached 45 \uJypb. We mapped 372 methanol masers with
peak flux densities of more than 2 Jy selected from the literature, 367 of them
were detected. Absolute positions have nominal uncertainties of 0.3 arcsec. 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 on all detected maser spots. The third catalog present derived data
of the 279 radio continuum sources found in the vicinity of maser sources.
Among them, 140 show evidence of physical association with maser sources. Our
catalogs list properties including distance, flux density, radial velocity and
the distribution of masers on the Galactic plane is then provided as well. We
found no significant relationship between luminosities of masers and their
associated radio continuum counterparts.
