Table 3 shows the result from the GALFIT analysis on the member galaxies of the six groups presented in the paper.

Table 3: Results from the GALFIT analysis on the member galaxies of our SCGs. The symbols used here have the same meaning as in Peng 2002; the position angle is measured from N to E counterclockwise. The magnitude is the total magnitude of the component, corrected for galactic extinction; errors on the measured magnitudes are of the order of 0.05 magnitudes and refer to the accuracy in the measurement of the zero-point plus the sky subtraction and the statistical error from GALFIT. Group SCG2159-3210 and galaxy SCG0122-3819 e have not been observed by us in the optical; for photometric measurement the reader is referred to Hickson et al. 1982 and to NED.

^a $r_{\rm e}$ is the effective radius of the Sersic or the deVaucouleurs's law, while r_s is the scale length of the exponential disk.
^b Diskiness (negative) or boxiness (positive) paramenter. It has no real meaning for central sources, so it is not reported for these cases.
^c Activity classification for HCG 90 is given in Coziol et al. (1998), while for all other groups, except SCG0141-3429, is from Coziol et al. (2000).
