Abstract:
The Hamburg Quasar Survey is a wide-angle objective prism survey for
finding bright QSOs in the northern extragalactic sky (|b|>20°;
δ>0°). The taking of the prism plates for 567 fields
covering this area was completed in 1997. Including direct plates for
fields with δ> 20° the plate archive contains now 1871
plates. In this paper we present a first list of 121 quasars, which
were verified by slit spectroscopy in the years 1986-1991, while
experiments to develop efficient selection techniques were made. The
sample contains objects with brightnesses 15≤B≤19.5 and redshifts
z≤2.8 collected over various parts of the sky, for which objective
prism plates were available at that time.

History:
* 16-Jan-1998: First version with 121 quasars.
* 02-Jun-1998 (from Dieter Engels): With respect to the printed version
the following changes were applied to the tables and figures:
The spectrum of the last quasar in table2-4.dat (Table 4 in the
paper), HS 2348+0438, was not included in the original Figures.
Instead the spectrum of another object, the probable quasar HS
1404+3203, originally not assigned for publication in this paper
entered Figure 13. The coordinates of HS 1404+3203 are 14 04 45.5
+32 03 31 (B1950). Its brightness is B=17.8±0.1 and the redshift is
z=2.4, provided that the strong emission line at 4130 Angstroem is Ly
alpha. The spectrum published requires verification. The total number
of quasars presented in this paper is now 122.
table2-4.dat was updated accordingly and the spectrum of HS 2348+0438
is provided as separate Postscript file.
