Summary of measured overdensities.
|Field||ρ||ρ d||δ||σ δ|
Notes. (1) QSO field. (2) Number of observed dropouts defined as objects with zTOT < 25, rAP > 27.2, i − z > 1.4. (3) Same as Col. 2, but corrected for the contamination from bluer objects caused by photometric errors (see text for details): these are the numbers adopted to compute the overdensities and their significance, shown in Cols. 4 and 5, respectively. (4) Overdensity , where , as estimated from the SXDS. (5) Significance of the measured overdensities (expressed in Gaussian-equivalent probabilities; see text for details).
