Notes. (a) The two components at 6 and 9 km s−1 cannot be distinguished because of the poor spectral resolution of the data (1.95 MHz). The total integrated flux is consequently only given for this transition. A similar flux is obtained for the N and M positions because of the low spatial resolution of the data (2.5″ × 2.1″).
