Notes. 

(a)

Different weighting schemes were used for continuum and line images. Major and minor axis and position angle are given.

(b)

rms noise in 1 km s-1 channel, continuum and integrated line maps (Figs. 2, 4, and 6). The noise is evaluated over a box from  − 2 to  − 1′′ in both RA and Dec relative to the phase center.
