Write:<<BOW ACO NNNN AANNNa>>
<<BOW Cl HHMM+DDMM NNN>>
N: about 6000
Object:G in ClG  (SIMBAD class: GtowardsCl = Galaxy towards a Cluster of Galaxies)
Note:In the format, 'AANNN' stands for: 'CCNNN' in each ACO Cluster Center, 'BFNNN' in each Blank Field corresponding to an ACO. In 1998ApJ...508L.139B, the authors found 2 galaxies 'ACO 370 CC24', and refer to them as 24a and 24b. For Cl clusters the format is 'NNN', without distinguishing center and blank field.
