We present data from a moderately deep spectroscopic Schmidt survey
(Blim = 17.5) of "active galaxies” selected by the presence of
emission lines in their spectra and/or their UV excess.
The redshift, magnitudes, color and diameter reduction methods have been
discussed in a previous paper. Here we explain the emission line equivalent
width determination method.
92 emission line objects have been found in two adjacent fields
(approximately 
) in the direction
of the southern extension of the
Virgo cluster. We give a catalog containing positions, photographic
R and B
magnitudes, 
colors,
effective diameters, redshifts, equivalent widths
and intensity ratios of the [OIII]
, H
and
[OII]
emission lines.
On these fields,
we evaluate the completeness limit of the survey at a pseudo B magnitude
value of 15.7.
A more elaborate astrophysical analysis will appear in a forthcoming paper.
