Up: Penetrating the "zone

1. Introduction

The significance of investigating the extragalactic sky in the "zone of avoidance" (ZOA) of the Galaxy, our search methods, and the material used for our survey (red sensitive POSSI-E prints) has been described and discussed in detail in previous parts of our series (Saurer et al. 1997 (part IV); Lercher et al. 1996 (part III); Seeberger et al. 1996 (part II), and Weinberger et al. 1995 (part I)).

A graphical overview of the status of our survey is shown in Fig.1 (click here). Not included in this figure is the recently started survey in the area around the Circinus Galaxy at tex2html_wrap_inline940, tex2html_wrap_inline942.

In this paper we present the results of our survey within the area tex2html_wrap_inline898, tex2html_wrap_inline900. This region is of special interest also because a branch of the Pisces-Perseus-Supercluster (PPScl) starting at (tex2html_wrap_inline948, b) tex2html_wrap_inline952 (tex2html_wrap_inline954, tex2html_wrap_inline956) and extending to the north is approaching the ZOA at tex2html_wrap_inline902, coming from the south (see, e.g., Focardi et al. 1984; Merighi et al. 1986; Meurs & Harmon 1988). Seeberger et al. (1994) could pursue this branch of the PPScl to tex2html_wrap_inline960. Mainly in the light of new doubt about the crossing of the main ridge of the PPScl (at tex2html_wrap_inline962) through the ZOA which was brought into discussion by Lu & Freudling (1995) it would be interesting to study this feature in more detail. For this purpose we have started to carry out radial velocity measurements by means of low resolution spectroscopy on a selected sample of galaxies at the southern and northern parts of the ZOA within this region.
