\caption{\label{lines}CO(3--2) intensities, velocities, and velocity dispersions from Gaussian fits
to the central positon of the sample of galaxies observed. Errors derived from the Gaussian fits  are indicated in parenthesis. The detections at two positions are indicated for He~2--10, at the offset position (20, 20) the parameters for the two lines detected are reported.}
