Abstract :We discriminated between the extragalactic objects insert ignore into journalissuearticles values(galaxies and quasars); and stars for Basle star fields, Plaut I, SA 54, and SA 82 by comparing Basle fields and APS POSS I finder charts. Their numbers are 187, 70, and 93 for Plaut I, SA 54, and SA 82, respectively. Most of these objects are apparently faint in V, and they cause an overestimated local luminosity function for absolutely faint magnitudes, Minsert ignore into journalissuearticles values(V); > 5. This effect is more conspicious for the field Plaut I.
