4 Appendix

In this appendix we present a few ELGs that were selected from our Region 1 (see Paper I) (the region of the Pisces-Perseus Supercluster) and Region 2. These objects were observed after the publication of the first catalogue and therefore were missed from our "List 1".

The observations were done in August 1995 with the Cassegrain Twin Spectrograph at the 3.5m telescope at Calar Alto, as a back-up of an observational campaign not dedicated to our project. The details of the observations are given in Table 6 while in Table 7 we list the name of the ELGs, alternative designations (for those objects contained in other catalogues), their coordinates (equinox 1950.0), heliocentric redshifts and emission-lines seen in their spectra. The abbreviations for alternative designations can be found in the List of Abbreviations used for the Table 2. The data reduction follows the same procedure as described in Sect. 2. The errors in the redshifts are around ${\Delta} z=0.0001-0.0002$. In order to have an external check of our redshift determination we also observed a few candidates that had redshifts in the literature. In Table 8 we give the names of the galaxies observed together with their velocities, both measured and from literature. In the last column we indicate the difference between our values and the reference one. Besides UM27, for which we obtained a big difference, the rest show differences up to 0.0001 in z. The finding charts of the newly discovered objects can be found in Fig. 2, upper panel.
