Table 7 lists the H isophotal fluxes and luminosities
estimated:
Column 1: Name of the galaxy (Hickson 1982);
Column 2: flux uncorrected for Galactic and Internal Extinction: (1) (erg cm-2 s-1);
Column 3: error about (1):
(erg cm-2 s-1);
Column 4: luminosity uncorrected for Galactic and Internal Extinction: (1) (erg s-1);
Column 5: error about (1):
(1) (erg s-1);
Column 6: flux corrected for Galactic Extinction (2)
(erg cm-2 s-1);
Column 7: error about (2):
(2)
(erg cm-2 s-1);
Column 8: flux corrected for Galactic and Internal Extinction for spiral
galaxies: (3) (erg s-1);
Column 9: isophotal area at 1 above the background:
(arcsec2);
Column 10: S/N ratio computed within the isophotal region defined by the
detection threshold.
In Tables 8 and 9 the fluxes are not corrected for Galactic and Internal Extinction. Such corrections can be simply derived from Table 7.
Table 8 lists isophotal corrected and adaptive aperture fluxes:
Column 1: Name of the galaxy (Hickson 1982);
Column 2: isophotal flux (erg cm-2 s-1);
Column 3: error about :
(erg cm-2 s-1);
Column 4: kron flux (erg cm-2 s-1);
Column 5: error about :
(erg cm-2 s-1).
In Table 9 we report the fluxes and luminosities of upper limits:
Column 1: Name of the galaxy (Hickson 1982);
Column 2: flux at 3 above the background (
)(erg cm-2 s-1);
Column 3: error about :
(erg cm-2 s-1);
Column 4: luminosity at 3 above the background (
)(erg s-1);
Column 5: error about :
(erg s-1).
We have compared the estimated ,
and
for the detected galaxies by using the Kolmogorov-Smirnov test: we found
they are drawn from the same parent population. The distributions of the three
different fluxes estimated for the detected galaxies are shown in Fig. 3. In
the following we make use of
in our considerations unless it is
differently specified.

In Fig. 4 the distribution of H isophotal luminosity
,corrected for Galactic Extinction and uncorrected for Internal Extinction, of the 73
detected galaxies (shaded histogram) is shown. We over-plot also the distribution of
H
upper limits to luminosity for the 22 undetected galaxies (dashed line).
