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.
