Notes. Column (1): Clump, Cols. (2)-(3): Peak position of the emission; Col. (4): Velocity range of the clump emission; Col. (5): Deconvolved angular diameter of the clump; Col. (6): Peak $T_{\rm mb}$ of the spectrum; Col. (7): Peak velocity of the spectrum; Col. (8): Deconvolved FWHM line-width of the spectrum; Col. (9): Integrated intensity emission from the FWHM contour of the clump; Col. (10): Far distance of the clump; Col. (11): Near distance of the clump; Col. (12): Galactocentric distance of the clump; Col. (13): Carbon isotope ratio; Col. (14): Oxygen isotope ratio.
(a) Deconvolved for the beam size; (b) deconvolved for the velocity resolution; (c) the parameters are derived from a high velocity resolution resample (0.5 km s-1); (d) the physical parameters are derived from the BU-FCRAO GRS data, because the clump is at the edge of our map; (e) the carbon and oxygen isotope ratios have been obtained using: ${^{12}\rm C}/{^{13}\rm C} = 7.5~D_{\rm GC}+7.6$ and ${^{16}\rm O}/{^{18}\rm O} = 58.8~D_{\rm GC}+37.1$ (Wilson & Rood 1994), where $D_{\rm GC}$ is the galactocentric distance (Col. 11).
