Teplitz H.I., Hill R.S., Malumuth E.M., Collins N.R., Gardner J.P., Palunas P., Woodgate B.E. =2001ApJ...548..127T ================================================================================ ADC_Keywords: Clusters, galaxy ; Photometry, UBV ; Photometry, Cousins ; Redshifts Keywords: cosmology: observations - galaxies: clusters: general - galaxies: evolution Abstract: We present the galaxy-galaxy angular correlations as a function of photometric redshift in a deep, wide galaxy survey centered on the Hubble Deep Field-South (HDF-S). Images were obtained with the Big Throughput Camera on the Blanco 4-m telescope at CTIO, of 1/2 square degree in broadband uBVRI, reaching ~24mag. Approximately 40,000 galaxies are detected in the survey. We determine photometric redshifts using galaxy template fitting to the photometry.

A unique flag image was created for each bandpass, then composite two-bit-deep masks were generated from pairs of flag images. The masks are used to distinguish sources flagged in a measurement image from those flagged in a detection image. 1: object flagged in the measurement image mask. 2: object flagged in the detection image mask. 3: object flagged in both detection and measurement image masks. Note (2): Flags of detection: 0-7, 16, 19, 20, 22, 23, 129, 133, 145, 149 -------------------------------------------------------------------------------- History: From http://hires.gsfc.nasa.gov/~research/hdfs-btc/ References: Palunas et al., Paper I 2000ApJ...541...61P ================================================================================ (End) Patricia Bauer [CDS] 17-Apr-2001
