Scientific paper

Two independent QSO surveys in Selected Area 94 have been completed and over 30 QSOs have been confirmed through slit spectra. From these data the success rate of finding real QSO is estimated at about 80 percent. The surface density of QSOs for B less than 19.5 is about 5.4/sq deg. The two-dimensional clustering of quasars is studied. Using the minimum interval statistics and the two-point correlation function, it is found that the distribution of the observed sample on the sky did not differ significantly from a random distribution. However, there was a weak clustering for low redshift quasars.
