So far this is the largest H catalogue of HCG galaxies having Hcalibrated fluxes. Such a sample constitutes a powerful tool to perform quantitative
analysis on the recent star formation rate inside HCG galaxies. We have derived the SFR
for the galaxies of our sample using the results of
which relate the SFR to H luminosity through the relation:
In Fig. 5 we show the distribution of SFR computed taking into account (dotted line) and without taking into account (solid line) Internal Extinction. The two distributions are quite similar, as confirmed also by a Kolmogorov-Smirnov test.
