Notes. Column 1 gives the name of the core as denoted by Tan et al. (2013). Column 2 gives the name of the parent clump as denoted by Butler & Tan (2012) and, in brackets, 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 3 gives the name of the IRDC in which the core is embedded. Columns 4 and 5 give the right ascension and declination of the core and Cols. 6 and 7 give the Galactic longitude and latitude of the core, based on the N2D+ detections of Tan et al. (2013). Column 8 gives the central velocity with respect to the local standard of rest of the core, as measured with the N2D+J = 3 → 2 line observed by Tan et al. (2013). The local standard of rest velocity of the parent cloud, from Simon et al. (2006), is given in Col. 9. Column 10 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 both IRDCs in this paper.
