Abstract:
We present a catalog of the 48 Voronoi Galaxy Cluster Finder (VGCF)
cluster detections. We provide a cluster ID, signal to noise ratios
(SNR) in the B, V, R and I bands, positions, angular radius of the
cluster, photometric redshift estimates (derived from color-magnitude
diagrams (CMD)) and PDCS redshift estimate (Postman et al.,
1996AJ....111..615P 1996AJ....111..615P), if available. Table 5 contains cluster
detections in F0028+0515, F0027+0555, F0228+0115 and F0226+0026 fields
and other two regions that overlap PDCS 0h and 2h fields.
Description:
We select 4 pointings for the Wide Field Camera (WFC) mounted at the
prime focus of the 2.5m Isaac Newton Telescope (INT), located at the
Roque de Los Muchachos Observatory, La Palma. We carried out
observations from October 12 to October 14, 1999.

--------------------------------------------------------------------------------
Note (1): special values of the signal-to-noise ratio:
0.00 = the cluster has not been identified in the corresponding band
blank space = no data at that position.
Note (2): Detection flag as follows:
A = detection in an overlap region between our fields and Palomar
Distant Cluster Survey PDCS0 or PDCS2 of 1996AJ....111..615P 1996AJ....111..615P
B = cluster identified in a region outside the PDCS fields
C = cluster in a PDCS region not overlapping our fields
Note (3): VNN corresponds to VGCF clusters that have their center within
another VGCF cluster
