CO survey of W51 molecular cloud
Listed in IVOA Registry (Virtual Observatory)
We present 38" resolution maps of the CO and ^13^COJ=2-1 lines in the molecular clouds toward the HII region complex W51.
Description
The maps cover a 1.25x1{deg} section of the galactic plane and span +30 to +85km/s (LSR) in velocity. The spectral resolution is ~1.3km/s.
The velocity range of the images includes all the gas in the Sagittarius spiral arm. Color figures display the peak line brightness temperature, the velocity-integrated intensity, and 2km/s channel-averaged maps for both isotopologs, and also the CO/^13^COJ=2-1 line intensity ratio as a function of velocity. The CO and ^13^CO line intensity image cubes are made available in standard FITS format as electronically readable tables.

We compare our molecular line maps with the 1.1mm continuum image from the BOLOCAM Galactic Plane Survey (BGPS; Aguirre et al. 2011ApJS..192....4A; Rosolowsky et al. 2010, Cat. J/ApJS/188/123). From our ^13^CO image cube, we derive kinematic information for the 99 BGPS sources in the mapped field in the form of Gaussian component fits.
The integrated ^13^CO line intensity and the 1.1mm source flux density show only a modest degree of correlation for the 99 sources, likely due to a range of dust and gas physical conditions within the sources. However, the 1.1mm continuum surface brightness and the integrated ^13^CO line intensity for small regions containing single BGPS sources and molecular clouds show very good correlations in many cases.
