Notes. Numbers in parentheses are uncertainties given by the fitting routine GAUSS-2D in units of the last digits.

(a)

Peak flux density and noise level measured in the integrated intensity map.

(b)

Signal-to-noise ratio.

(c)

Size of synthesized beam (HPBW) and position angle (east from north).

(d)

Size (FWHM) and position angle of the fitted Gaussian.

(e)

Equatorial offset with respect to phase center (see Sect. 2.1).

(f)

Deconvolved major and minor diameters of the emission (FWHM) and position angle.

(g)

Average deconvolved size of the emitting region.

(*)

The line is a group of transitions from the same molecule blended together.
