Notes on the Clusters
- A119
- A peak between 9000 and 12000 km/s is localized within the cluster. I have removed those velocities as foreground elements (e.g., Fabricant, et al. AJ 105:3 788 1993) See Table 2 and Table 4 for dynamical information including these cut galaxies.
- A151
- There are two other clusters to the south at velocities of 12500 km/s and 30000 km/s.
- A179
- 3 velocities from source F
- A505
- empty field, 4 galaxies in cluster
- A569
- There is another cluster centered about 7h8m and 50.2d (B1950), to the north of A569.
- A634
- Another cluster lies at edge of field at z=5700 km/s; the cluster is possibly double with a peak between 6500-7700 km/s, east of the main cluster.
- A838
- 2 velocities
- A979
- A galaxy at z~19000 km/s may be in the cluster. Dynamical information of the cluster with this galaxy may be found in Table 2 and Table 4.
- A993
- This cluster has a large spread in velocities, 9000-18000 km/s.
- A1016
- There are two clusters: the one labelled 'A' has a velocity range of 9000-12000 km/s, and 'B' has a range of 12000-17000 km/s.
- A1069
- A peak at 16000-17000 km/s may be in the cluster. Dynamical information for the cluster with this peak is in Table 2 and Table 4.
- A1225
- 2 velocities
- A1254
- There is confusion over cluster location. On the DSS image, the cluster appears to the west of Abell coordinates, but may be confused with brighter galaxies to the east. The data from ZCAT lists one galaxy in the cluster, at z=45564 km/s. An X-ray source is found at 11h27m25.00s +71d07m24.5s (ROSAT, J2000).
- A1257
- The center appears to lie offset from the Abell coordinates at 11h24m30s and 35.75d.
- A1270
- 1 velocity, no dispersion The center appears to lie offset from the Abell coordinates at 11h26m25s and 54d24m (B1950). Another cluster sits at 11h27m55s and 54d18m23s (B1950).
- A1436
- 3 velocities
- A1736
- There are two clusters, one at 9000-11400 km/s, labelled A, and one at 11400-16000 km/s, labelled B.
- A1890
- 3 velocities
- A2052
- There is another cluster in the western part of the field, 12000-16000 km/s, as well as to the north-east (A2063).
- A2063
- There is a background cluster in the field, to the south, at 12500-16000 km/s.
- A2147, A2151, A2152
- are all on same field.
- A2148
- There is no clearly identifible cluster on the histogram, and the galaxies that appear in the spatial plot have a large spread in velocity.
- A2162
- There are two clusters; the one labelled 'A' is within the velocity range of 8500-12000 km/s, while 'B' has a 12000-17500 km/s velocity range.
- A2248
- 2 velocities
- A2249
- 3 velocities
- A2255
- has foreground galaxies superimposed upon the cluster.
- A2319
- has background galaxies superimposed upon the cluster.
- A2626
- There are 3 clusters on the field. The main cluster, A, has a redshift of z=.055. Superimposed upon this cluster, or maybe slightly to the south of it, is a background cluster, B, at z=20000 km/s. To the northeast, at 23h36m30s and 21.2d, is another background cluster, C, at z=20000 km/s. This cluster may be in A2637, which is not in our cluster sample.
- A2630
- 3 velocities
- A2731
- 3 velocities
- A2824
- While the cluster appears on the DSS image, there is no data for it in ZCAT. In addition, a cluster appears offset at 48m and 22.25d (B1950) at the redshift listed for A2824.
- A2870
- is on same field as A2877, which lies to the north.
- A2877
- appears on the same field as 2870.
- A3193
- A background cluster appears at 25000 km/s.
- A3301
- 4 velocities
- A3389
- The histogram for A3389 has a long, upper tail; we chose to cut outliers at 12000 km/s.
- A3537
- There are two clusters, one labelled A at 6500-12500 km/s and one labelled B at 12500-18500 km/s.
- A3558
- appears as the middle cluster in a line of 3 or more clusters.
- A3560
- While centered by Abell by a bright galaxy, the distribution of galaxies in A3560 appears to be to the east of Abell coordinates.
- A3571
- occupies same field as A3571 and A3575.
- A3572
- occupies same field as A3572 and A3575.
- A3575
- occupies same field as A3572 and A3571.
- A3577
- Galaxies with velocities between 11000-12000 km/s may be cluster members. See Table 2 and Table 4 for dynamical information including these galaxies.

- A3716
- A cluster appears to lie directly to the north of A3716.
- A3799
- 3 velocities
- A3826
