Target Selection {#targets}
----------------

The first column of Table \[info\] lists each core observed, in order of Right Ascension. This survey is designed to provide a complementary dataset to the c2d observations of low-mass dense cores; thus most of our targets are selected from the list of cores observed by that project. For the earlier observation runs that occurred before the *Spitzer* data was available, we chose what we believed to be the most scientifically interesting cores from the Molecular Cloud Cores Database[^2], created by members of the c2d team at the Harvard-Smithsonian Center of Astrophysics (CfA). However, not all of these cores made the final *Spitzer* target list, so some of the cores in our sample do not have corresponding *Spitzer* data. Once the *Spitzer* data became available, we focused on cores found to be interesting and worthy of follow-up submillimeter observations. In addition to the observations of dense cores, c2d also obtained
