Notes. (a) The synthesised beam size and its PA. (b)FWHM of a Gaussian fit to the brightness distribution of the integrated line profile (and deconvolved with the beam). (c) FWHM of a Gaussian fit to the line profile (deconvolved with the spectral resolution of 1.5 km s−1). (d) This line is double-peaked and the results of the Gaussian fit are only indicative.
