Notes. Columns (2)–(10) of this table are as follows: (2) LSR velocity; (3) FWHM linewidth; (4) one-dimensional non-thermal velocity dispersion; (5) the ratio of the non-thermal velocity dispersion to the isothermal sound speed; (6) peak line intensity; (7) integrated intensity; (8) total C17O column density; (9) fractional abundance of C17O; (10) CO depletion factor (only towards the “main” velocity components).

(a)

The additional velocity components are labelled with “(2nd)”.

(b)

The velocity range used in the calculation is given in square brackets. The percentage value for G2.11-C(2nd) and G11.36-F(2nd) indicates the contribution of hf components’ intensity lying within the detected line.
