Abstract:
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. 92 emission
line objects have been found in two adjacent fields (approximately
50deg2) in the direction of the southern extension of the Virgo
cluster. We give a catalog containing positions, photographic R and B
magnitudes, U-R colors, effective diameters, redshifts, equivalent
widths and intensity ratios of the [OIII]λλ4959,5007,
Hβ and [OII]λ3727 emission lines. On these fields, we
evaluate the completeness limit of the survey at a pseudo B magnitude
values of 15.7. A more elaborate astrophysical analysis will appear in
a forthcoming paper.
