The Arizona radio observatory CO mapping survey of galactic molecular clouds. II. The W3 region in CO J = 2-1, 13CO J = 2-1, and CO J = 3-2 emission. Bieging J.H., Peters W.L. <Astrophys. J. Suppl. Ser., 196, 18 (2011)> =2011ApJS..196...18B
ADC_Keywords: Molecular clouds ; Radio lines ; H II regions ; Interstellar medium ; Millimetric/submm sources Keywords: H II regions - ISM: clouds - ISM: individual objects (W3) - ISM: kinematics and dynamics - ISM: molecules Abstract: We present fully sampled 38" resolution maps of the CO and 13CO J=2-1 lines in the molecular clouds toward the HII region complex W3. The maps cover a 2.0°x1.67° section of the galactic plane and span -70 to -20km/s (LSR) in velocity with a resolution of ∼1.3km/s. The velocity range of the images includes all the gas in the Perseus spiral arm. We also present maps of CO J=3-2 emission for a 0.5°x0.33° area containing the HII regions W3 Main and W3(OH). The J=3-2 maps have velocity resolution of 0.87km/s and 24" angular resolution. Color figures display the peak line brightness temperature, the velocity-integrated intensity, and velocity channel maps for all three lines, and also the (CO/13CO) J=2-1 line intensity ratios as a function of velocity. The line intensity image cubes are made available in standard FITS format as electronically readable files. We compare our molecular line maps with the 1.1mm continuum image from the BOLOCAM Galactic Plane Survey (BGPS). From our 13CO image cube, we derive kinematic information for the 65 BGPS sources in the mapped field, in the form of Gaussian component fits. Description: Observations were made with the Heinrich Hertz Submillimeter Telescope (HHT) on Mt. Graham, AZ; in several observing sessions from 2005 June to 2008 April. The J=2-1 lines of the CO isotopologues 12C16O (hereafter CO) and 13C16O (hereafter 13CO) were mapped over a 2.00°x1.67° field covering the galactic coordinate ranges l=132.5° to 134.5°, b=0° to +1.67°.
