Table 5

Average values (with the standard deviation in parentheses) of the histograms (see Appendix C) of each velocity (firstmoment) difference map.

Notes. All units are km s−1. For G24, HNCO (1) is used instead of HNCO (2). G17 and G345 Main have only one HNCO transition, so the internal error for HNCO transitions cannot be determined.
