Paper I presented integrated apparent and absolute B luminosities as well as isophote 24 magarcsec -2 magnitudes.
Different symbols stand for distinct morphological types.
Mean effective surface brightness versus absolute magnitude. Ellipses show the median and standard deviation of each parameter for the different morphological types All the above information has been used to perform the morphological classification of the UCM galaxies. Our galaxies are characterized by shorter disks than those of normal spirals. Besides, they seem to be objects with a high luminosity concentration. Finally, a size-luminosity correlation has been outlined.
