Notes. Mean values and standard deviations are determined considering only Hi detected galaxies and CO upper limits as detections; for late-type galaxies, means are determined using only unperturbed galaxies with Hi − def < 0.4. The number in parenthesis in each morphological class gives the number of objects used to determine the mean values.
