3 The catalogue

The observed objects are listed in Table 2. The table is organised as follow:

• Column (1) gives the name of our objects, which are designated by the prefix HS (from Hamburg Survey), followed by the first four digits of the 1950.0 right ascension and declination.
• Column (2) gives alternative designations for those galaxies contained in other catalogues. The abbreviations are explained in the List of Abbreviations.
• Columns (3) and (4) give the 1950.0 positions. The coordinates are derived from the Hamburg direct plates and have an accuracy of $\pm 2^{\prime\prime}$.
• Column (5) gives the heliocentric redshifts.
• Column (6) contains a flag S (from selection) that gives the selection criteria used to select the candidates from the objective prism spectra: E for emission candidate (first priority) and B for blue candidate (second priority) (see Paper I).
• Column (7) contains special remarks.

Table 2 contains 39 galaxies, of which 33 are ELGs and 6 are galaxies with absorption lines. The later came only accidentally into our sample, as failures of our selection procedure. Three objects were previously known as IRAS sources and of these, two were also radio sources. From the 39 galaxies from our Table 2 only three were already known in the literature with available redshifts. These objects were therefore not reobserved, and the redshift given in the table is taken from literature.

One object from our catalogue, HS1337+3941 happens to be a very nearby dwarf galaxy. With a redshift of z = 0.0025, this galaxy entered into our sample only as a second priority object (see Paper I for the selection flag $\rm S=E$). It has a very faint [OIII] 5007 line and would be better detected by an H${\alpha}$ survey.

Remarks on Table 2:

${\ast}$ The galaxy HS1312+3112 has a galactic star superimposed on the North-Eastern side of its image.
${\ast\ast}$ HS1506+4303 and HS1509+4409 were observed with the Twin Spectrograph, with the same set-up as given in Table 6 (see Appendix).

Table 5: List of identified stars

Finding charts of all our newly discovered objects can be found in Fig. 1. We also give the finding charts of some of our objects that were previously known as IRAS sources. The finding charts were prepared by means of the Palomar Sky Survey plates, digitised and distributed on CD-ROM by the Space Telescope Science Institute. Fields are 10$^{\prime} \times 10^{\prime}$. North is up, and east is to the left.

The identified emission (absorption) lines of all the newly discovered galaxies are listed in Table 3 while those objects which are certainly stars are listed in Table 5.

On our long-slit spectra we found some further emission-line objects projected near to our targets. These galaxies had good enough signal-to-noise to be fully reduced and they are listed in Table 4. They were not detected on the Hamburg objective plates because their redshift is higher than z = 0.078, which is the limit for which the [OIII]${\lambda}$5007 line can be detected due to the cut-off of the IIIa-J emulsion at 5400 (see Paper I for selection effects). These galaxies are designated by the prefix HS followed by the first four digits of the 1950.0 right ascension and declination, plus the suffix N (from neighbours). Their finding charts can be found in Fig. 2, lower panel.
