Notes. Column 1 gives the name of the clump as denoted by Butler & Tan (2012) and, in parenthesis, the original name of the clump as assigned by Rathborne et al. (2006). The F2 clump was not given a designation by Rathborne et al. (2006). Column 2 gives the name of the IRDC in which the clump is embedded. Columns 3 and 4 give the right ascension and declination of the clump and Cols. 5 and 6 give the Galactic longitude and latitude of the clump, as given by Butler & Tan (2012). Column 7 gives the velocity with respect to the local standard of rest of the parent IRDC, as given by Simon et al. (2006). Column 8 gives the kinematic distance of the cloud from Simon et al. (2006). While Kurayama et al. (2011) find a 1.56 kpc distance for IRDC F, containing F1 and F2, Foster et al. (2012) find a distance consistent with the kinematic distance for IRDC F, based upon extinction measurements. We thus elect to use the kinematic distances from Simon et al. (2006) for all four clumps in this paper.
