Description:
The largest survey of compact galaxy groups was published by
Shakhbazian et al. (see cat. <VII/89>). This catalogue provides
accurate positions of individual galaxies in the groups; photometrical
properties of the Southern sky (delta not greater than +2{deg}30') are
evaluated on the basis of the COSMOS/UKST catalog of the Southern sky.
The catalogue contains 373 groups; this number differs from the
number in Shakhbazian's list (377 groups) by the following:
=> No data for groups
001 (there were already published data by other authors),
206 (could not be re-identified)
241 (could not be re-identified)
252 (is identical with 214),
301 (could not be re-identified)
353 (could not be re-identified)
=> Group 328 was published twice (in North and South)
=> Group 340 was divided in two parts (340 and 340a), according
to Bettoni and Fasano ([BF95]=1995AJ....109...32B)

Note (1): Individual Notes on the groups:

006 = A 1218
016 = I Zw 167, ARP 330

026 = A 1143
038 = III Zw 022
040 = A 0193
053 = A 1050
054 = A 1067
065 = A 1284
078 : probably stars
166 = UGC 10638, part of A 2247
191 = A 1097

233 = A 1082?
360 = A 2113
361 = A 2524
362 = III Zw 108
Note (2): In general the coordinates of the groups were calculated
from DSS. The 'H' indicates positions adopted from the Hamburg
Quasar Survey, and the question mark (?) indicates an inaccurate
position (a note generally follows)
Note (3): when only the velocity was given in the paper, the redshift
was computed with z = V / 299792
