Notes. The full table is available in electronic form at the CDS. Columns are identifier, galactic longitude, galactic latitude, right ascension, declination, peak flux, radius as calculated by CLUMPFIND, integrated flux, NH3 velocity from Wienen et al. (2012), flag indicating presence of direct NH3 observation, HCO+ velocity from Schlingman et al. (2011), flag indicating presence of direct HCO+ observation, calculated near distance, calculated far distance, peak column density, mass calculated for the near distance, mass calculated for the far distance, flag indicating the connection to an IRDC. Negative near distances are meaningless; the velocities of those sources place them in the outer Galaxy, while we are looking towards the inner Galaxy. However, their galactic latitude and velocities are also consistent with the near 3 kpc arm at a distance of 5.2 kpc (Dame & Thaddeus 2008). The NH3 flag means that Wienen et al. (2012) have observed a position within the clump’s boundary definition. If the NH3 flag is absent but a NH3 velocity is given, the velocity is derived from neighboring clumps (see Sect. 5 for details). The same yields for the HCO+ flag and HCO+ observations in Schlingman et al. (2011).
