A quality rating was assigned to the results from each spectrum, on the basis of the
cross-correlation results, and also after visual inspections of the spectra.
Quality ratings were made as follows: Q = 1 for excellent spectra (S/N per
20; mean
30);
Q = 2 for good spectra (mean S/N
16); Q = 3 for acceptable spectra (mean S/N
11); and Q = 4 for poor spectra (S/N < 10; mean S/N
4).
The mean Tonry & Davis r values for the four quality ratings are
23,
17,
13, and
7 for ratings of
= 1, 2, 3, and 4 respectively.
The percentage distribution of the quality ratings is shown in Table 4. For the spectra in the
three sample regions, 78% of the spectra are of quality 1 or 2.
The S/N required to obtain a good measurement of radial velocity is lower than the S/Nrequired to obtain a reliable velocity dispersion. For the galaxies with Q = 4 the signal was not
strong enough to enable a reliable determination of the velocity dispersion. This was the case
for galaxies of low surface brightness for which it was difficult to obtain spectra with a high
enough S/N ratio. From these weak spectra, only redshifts were found, and these galaxies
were not included in the sample used for distance determination.
Below a certain limit, the values of velocity dispersion are less reliable. In the final sample we
used only galaxies with high enough
values to be determined accurately.
The lower limit on usable
values depends on the instrumental resolution. For the
spectra taken at MDM, with a dispersion of
/pix and an instrumental
resolution of
km s-1, only velocity dispersions which are larger than
130 km s-1 can be measured reliably. For the spectra from the MMT, for which the
dispersion was
/pix and the instrumental resolution was
km s-1, the limit is lower.

Figure 10: Comparison of results for heliocentric radial velocity with published data for 32 standard galaxies and 20 sample galaxies |
Spectroscopic results for the sample galaxies are given in Table 5.
The columns in the table are as follows:
1. Galaxy number in the APM catalog (or the galaxy name from the NGC or CGCG catalog in
a few cases); the first three digits of the APM galaxy number are the UK Schmidt plate number.
2 & 3. Right Ascension and Declination (epoch J1950.0) taken from the APM catalog.
4 & 5. Magnitude bJ (in mag) and major-axis diameter d (in arcmin) from the APM
catalog (both values corrected for Galactic extinction). Preliminary values prior to final calibrations.
6. Heliocentric redshift
(in km s-1).
7. Estimated internal error in
(in km s-1).
8. Central velocity dispersion
(in km s-1).
9. Estimated internal error in
(in km s-1).
10. Quality rating
for the spectrum.
In Table 5, the galaxies are ordered by magnitude, with a few exceptions. The galaxies CGCG2158 (in Region 1) and NGC 7010 (in Region 2) were added for completeness. In Region 1, the galaxy denoted 87101109E is the elliptical galaxy close to 87101109, which was found to be a spiral. Also included are some galaxies from plates which are not in the final APM catalog: two galaxies from plate 728 in Region 1, and four galaxies (from plates 885, 887, and 889) in Region 2 (no magnitudes are given for these galaxies, since the magnitude zero-pointing and plate-matching calibration was not done for these plates). In Region 3, there are eight extra galaxies: a group near 61101581 and a group near 61101081, for which spectra had been obtained, and which were included in the sample.
The results for the spectroscopic parameters of the standard galaxies and Coma galaxies are presented in Tables 6 and 7 respectively. The columns are as in Table 5, except that magnitudes and major-axis diameters are not given. The names of the galaxies in Coma are taken from the Dressler numbers as catalogued by Dressler (1980).
