Notes. The columns are (from left to right): the source designation, the equatorial source coordinates, the heliocentric distances, distance reference, systemic velocity of the source, FWHM of the synthesised beams (θmaj × θmin), position angles (PA), and FWHM of the restored circular beams (θB) and the root-mean-square (rms) noise levels of the line and continuum maps, respectively.
