$^a$ $D$ is the maximum vertical deviation between two cumulative distribution in the K-S statistics. \\
$^b$ $P$ gives the significance level of the K-S statistic. Small values of $P$ show that the cumulative distribution function of CS is significantly different from intragroup regions. \\
$^c$ Colors of HCG~100 objects from de~Mello et~al. (\cite{dem08a}) were estimated using fixed aperture. \\ 
$^d$ Using HCG 100 detected regions from this work. \\
$^e$ Using HCG 100 detected regions from de~Mello et~al. (\cite{dem08a}).
