The main objective of the ENACS programme was to drastically increase the number of redshifts for galaxies in rich Abell clusters. The direct goal was to construct a complete, volume-limited sample of at least 100 rich Abell clusters, for which the ENACS data, in combination with data already in the literature, would provide good kinematical data. Consequently, the main observational effort of the ENACS consisted of multi-object spectroscopy. In addition, CCD-imaging was done to calibrate the photographic photometry which formed the basis for the selection of the galaxies to be observed spectroscopically.
In Paper I we have discussed the definition of the cluster sample, and the selection of the galaxies in the direction of the clusters to be observed with Optopus. In that paper, we also described the methods employed in the determination of the redshifts, and of the magnitudes. Here we present the positions and redshifts of all 5634 ENACS galaxies, as well as the red magnitudes of 5615 ENACS galaxies, and we give the estimated errors in the redshift estimates. For the redshifts derived from absorption lines using cross-correlation with template spectra (see Paper I, and Tonry & Davis 1979), we also give the S/N-ratio of the peak in the correlation function. As shown in Paper I, this S/N-ratio allows one to estimate the reliability of the redshift. For about one-fifth of the galaxies we could estimate the redshift from emission lines, either exclusively or in addition to an absorption-line redshift. For all galaxies with clear emission lines in the spectrum, we give information about which lines were seen, and the approximate line ratios (using an excitation code) as well as on the presence or absence of features in the continuum.

In Table 1 (click here) we show a summary of the catalogue; the total catalogue is available electronically from the CDS (and by anonymous ftp from: 132.229.214.2 as pub/katgert/enacs.cat, or from: 193.50.128.3 as amazure/enacs/enacs.cat). In Table 1 (click here) we give the results for one galaxy in each of the redshift surveys in the direction of the 107 target ACO clusters. By choosing the last entry in each survey we implicitly show the total number of redshifts measured towards a cluster.
The organization of Table 1 (click here) is as follows:
Column (1): sequence number of cluster in ACO catalogue (Abell et al. 1989)
Column (2): sequence number of galaxy in redshift survey of cluster (= total number of redshifts in the survey)
Column (3): right ascension (equinox 1950.0)
Column (4): declination (equinox 1950.0)
Column (5): R25, i.e. the isophotal R-magnitude within the 25 mag/arcsec2 isophote (a value of 0.00 means: not available)
Column (6): the adopted heliocentric velocity, cz, of the galaxy
Column (7): the estimated error in the adopted heliocentric velocity
Column (8): the heliocentric velocity, , of
the galaxy
based on absorption lines (a value of 0 means: not
available)
Column (9): the signal-to-noise ratio of the peak in the
cross-correlation function used to derive
(a value of 0.00 means: not available)
Column (10): the heliocentric velocity, , of
the galaxy
based on emission lines (a value of 0 means: not
available)
Column (11): code indicating the presence of emission lines,

For a description of the methods employed in determining positions, magnitudes, redshifts and redshift errors we refer the reader to the relevant sections of Paper I. Note that among the 666 galaxies with both an emission- and an absorption-line redshift we have 80 cases in which the two redshift estimates are discordant (i.e. differ by more than 500 km/s). In these 80 cases we have derived the ENACS redshift according to a simple scheme which takes into account the estimated reliabilities for different categories of redshift estimates (see Sect. 4.3 in Paper I for more details). This scheme generally (but not always) selects the most probable value, but it does not take into account the redshifts of other galaxies in the cluster. Therefore, we list both redshift estimates.
While measuring the wavelengths of the emission lines, the relative intensities were also estimated. An indication of the line ratios is summarized in the Excitation Code. In view of the difficulties associated with estimating equivalent widths, especially for the narrow oxygen lines, the code in Col. 12 of Table 1 should be used with caution. On the other hand, the Excitation Code for AGN is thought to be quite reliable; in other words: this code was assigned only if there was little or no doubt about the AGN character of the ENACS spectrum of the object. As a consequence, it is possible that not every AGN in the catalogue has been assigned the AGN Excitation Code, because it is not certain that we have been able to recognize unambiguously all AGN as such from their ENACS spectrum.
Finally, for the galaxies with emission lines in their spectrum, an indication is frequently (but not always) given about the presence or absence of features in the continuum spectrum. When this Continuum Index is 0, this simply means that the quality of the spectrum was not sufficient for a reliable statement about the character of the continuum.
After the spectroscopic observations for the ENACS were done, we became aware of published redshifts for 33 galaxies without ENACS redshift, in the "Optopus areas" of the four ENACS clusters A168, A957, A1809 and A2052. Most of these 33 galaxies (viz. 21 of them) were in the galaxy catalogues that we prepared for the Optopus observations, so that we have positions and magnitudes for them in the same systems as for the ENACS galaxies. Some of these galaxies had been observed by us with Optopus, but without yielding a redshift; others were not observed. The remaining 12 (predominantly faint) galaxies for which non-ENACS redshifts have been published were not in our galaxy catalogues, and no magnitudes are available for them.
As these galaxies may be of interest in certain types of analysis (some are among the brightest galaxies in their parent cluster), we have listed all 33 in Table 2. The organization of Table 2 is as follows:
Column (1): sequence number of cluster in the ACO catalogue (Abell et al. 1989)
Column (2): right ascension (equinox 1950.0)
Column (3): declination (equinox 1950.0)
Column (4): R25, i.e. the isophotal R-magnitude within the 25 mag/arcsec2 isophote (0.00 means: not available, i.e. the galaxy is not in the catalogue we prepared for the Optopus observations)
Column (5): the heliocentric velocity, cz, of the galaxy
Column (6): the estimated error in the heliocentric velocity
Column (7): reference to source of redshift.
