Abstract (from CDS):
From the measured parameters, Gaussian reconstructions of the emission are carried out, and these compare favorably to the raw data. A detailed analysis of the decomposition in complex regions is performed, showing that severe truncation at levels much in excess of 0.8 K is countered by the operation of a ``thermostat'', resulting in concatenation of emission into a larger object if severe blending is present, rather than the identification of a number of smaller, more heavily truncated objects. Two other tests are carried out: (1) an association test that examines the utility of using the decomposed 12CO (J=1-0) emission, in comparison to CS emission, to identify possible sites of star formation as traced by IRAS point sources; (2) a test comparison of 12CO and 13CO decompositions to gauge the effects of emission saturation and blending. Overall, the results of these two tests show that emission enhancements in 12CO (J=1-0) emission, induced by internal heating by embedded star formation, are in general usefully recorded in the decomposition, but that emission blending and saturation on scales of ∼few arcminutes in complex regions can limit the precision to which associations with other tracers can be made. A statistical approach to source association that makes good use of the information contained in the catalog is developed and described.
The new 12CO cloud catalog, as a concise description of the OGS data, will facilitate intercomparisons of molecular clouds with other ISM components, available at comparable resolution within the Canadian Galactic Plane Survey. The catalog covers the Galactic longitude range 102°.5 to 141°.5, Galactic latitude range -3° to +5°.4, and lsr velocity range +20.8 to -120.2 km.s–1 and contains 14,592 objects. Due to its size, and for ease of access, the catalog is made available in electronic form.
