1998A&AS..128..507E The Hamburg Quasar Survey. II. A first list of 121 quasars. Engels D., Hagen H.-J., Cordis L., Koehler S., Wisotzki L., Reimers D. Received May 26;accepted August 21, 1997 Abstract. The Hamburg Quasar Survey is a wide-angle objective prism survey for finding bright QSOs in the northern extragalactic sky (|b|>20{deg}; {delta}>0{deg}). The taking of the prism plates for 567 fields covering this area was completed in 1997. Including direct plates for fields with {delta}> 20{deg} 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.

A first list of 121 quasars" [Astron. Astrophys., Suppl. Ser., Vol. 128, No. 3, p. 507 - 523 (Mar 1998)]. D. Engels, H.-J. Hagen, L. Cordis, S. Kohler, L. Wisotzki, and D. Reimers Astron. Astrophys. Suppl. Ser, 128 (1998) 507-523 The spectrum of the last quasar in Table 2, 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 Fig. 13. The coordinates of HS 1404+3203 are 140445.5 +32033, (B1950). Its brightness is B = 17.8 +/- 0.1 and the redshift is z = 2.4, provided that the strong emission line at 4130 A is Ly{alpha}. The spectrum published requires verification. The missing spectrum of HS 2348+0438 is given in the figure below. The total number of quasars presented in this paper is now 122. Finding charts and spectra in FITS format are available on our Web pages.
