Spectra of line 1 at 222.014 GHz (Table 2) extracted from the extended configuration array. The extraction diameter (in arc sec) is given in parentheses below the source name in the upper left corner of each spectrum. The observed frequency is converted to the LSR frame using the catalog line rest frequency given in Table 2. The blue vertical line indicates the adopted new LSR systemic velocity (see Table 1). The red vertical line shows the LSR velocity for the slightly different frequency determined in this work (see Table 2).
