Description

The results of a visual search for emission line and UV continuum objects on United Kingdom Schmidt telescope (UKST) objective prism plates are presented. 325 QSO candidates were found. Finding charts are given for all the QSO candidates. Redshifts estimated from the objective prism plate have been assigned to 243 of the objects and Bsub(J) magnitudes are given for most of the QSO candidates. N(m) and N(z) distributions are presented for these candidates and for all those from the 100 square degrees now searched on UKST objective prism plates. The slope of the cumulative counts with magnitude is 0.80 over the range 18.0-19.5 mag implying a similar form of evolution to that of radio sources. (author)
