VII/201      Cross-Identifications in Abell and Zwicky clusters (Kalinkov+ 1998)

Cross-Identifications in the Abell and Zwicky clusters of galaxies Kalinkov M., Valtchanov I., Kuneva I. <Bull. Inf. CDS 49 (unpublished)>
ADC_Keywords: Clusters, galaxy ; Cross identifications Description: A new identification between Abell and Zwicky clusters of galaxies and vice versa is completed. Two convenient files are generated with necessary data for comparing both catalogs; remarks on the cluster matching are also included. File Summary:

1- 4 I4 --- Abell [1/2712]+ Abell cluster designation 6 A1 --- Cflag *[cn] 'c' indicates a comment in file azrem.dat 8- 10 I3 --- Field Field where Abell cluster center lies on 12 A1 --- Code *[012+n]! Code for correspondence between A- and Z-clusters 14- 17 I4 --- ZCl [1/9133]? Zwicky cluster designation 19- 22 F4.2 deg Rab Abell cluster radius 24- 27 F4.2 deg Delta ? Angular distance between Abell and Zwicky clusters centers 29- 32 F4.2 deg Rz ? Zwicky cluster radius 34- 37 F4.2 deg Rabc Abell cluster radius with cosmology 39-118 A80 --- Znames Up to 10 names (field and consequent number in that field)
Note on Cflag: 'c' indicates that a comment exists in file azrem.dat 'n' indicates that no Zwicky cluster exists toward the Abell one. Note on Code: There are four possibilities: '0' : no matching, '1' : Abell cluster identical with Zwicky cluster, '2' : one Abell cluster is equal to two Zwicky clusters, '+' : two or more Abell clusters are equal to one Zwicky cluster.

Note on Text: The codes in comments are with respect to the Abell cluster: 'hb': half background Zwicky or Abell cluster, 'hf': half foreground, 'he': half equidistant, 'f' : foreground, 'b' : background, 'e' : equidistant, 'n' : no Zwicky cluster towards the Abell cluster.

Note on Text: several lines of comments may exist for a cluster; the ZCl number if then repeated. The codes in comments are with respect to the Zwicky cluster: 'hb': half background Abell or Zwicky cluster, 'hf': half foreground, 'he': half equidistant, 'f' : foreground, 'b' : background, 'e' : equidistant.
