\caption{Limiting values. These are the values of the limits of the
morphological classes.  The values are valid for the SDSS $g$ and $r$ bands.
The value for the $i$ band is the same as in the other filters for
$\varepsilon$.   For CI it is slightly higher because $i$ is more sensitive for
the dominant redder bulge stars. In this case one should add a value of 0.1
to the numbers of the CI in this table. In general, note that the galaxies
near boundaries have the least certain classification.}
