Description


We present 107 maps of continuum emission at 350{mu}m from Galactic molecular clumps. Observed sources were mainly selected from the Bolocam Galactic Plane Survey (BGPS) catalog, with three additional maps covering star-forming regions in the outer Galaxy. The higher resolution of the SHARC-II images (8.5" beam) compared with the 1.1mm images from BGPS (33" beam) allowed us to identify a large population of smaller substructures within the clumps. A catalog is presented for the 1386 sources extracted from the 350{mu}m maps. The color temperature distribution of clumps based on the two wavelengths has a median of 13.3K and mean of 16.3+/-0.4K, assuming an opacity law index of 1.7. For the structures with good determination of color temperatures, the mean ratio of gas temperature, determined from NH_3_ observations, to dust color temperature is 0.88 and the median ratio is 0.76. About half the clumps have more than 2 substructures and 22 clumps have more than 10. The fraction of the mass in dense substructures seen at 350{mu}m compared to the mass of their parental clump is ~0.19, and the surface densities of these substructures are, on average, 2.2 times those seen in the clumps identified at 1.1mm. For a well-characterized sample, 88 structures (31%) exceed a surface density of 0.2g/cm2, and 18 (6%) exceed 1.0g/cm2, thresholds for massive star formation suggested by theorists.
