Abstract:
We have conducted a deep multicolor imaging survey of 0.2deg2
centered on the Hubble Deep Field North (HDF-N). We shall refer to
this region as the Hawaii HDF-N. Deep data were collected in U, B, V,
R, I, and z' bands over the central 0.2deg2 and in HK' over a
smaller region covering the Chandra Deep Field North. The data were
reduced to have accurate relative photometry and astrometry across the
entire field to facilitate photometric redshifts and spectroscopic
follow-up. We have compiled a catalog of 48858 objects in the central
0.2deg2 detected at 5σ significance in a 3" aperture in
either R or z' band. Number counts and color-magnitude diagrams are
presented and shown to be consistent with previous observations. Using
color selection we have measured the density of objects at 3<z<7.
Our multicolor data indicates that samples selected at z>5.5 using
the Lyman break technique suffer from more contamination by
low-redshift objects than suggested by previous studies.
Description:
To optimize our data collection, observations were conducted on a
variety of instruments. The U-band data were collected using the Kitt
Peak National Observatory (KPNO) 4 m telescope with the MOSAIC prime
focus camera. The B-, V-, R-, I-, and z'-band data were collected
using the Subaru 8.2 m telescope and Suprime-Cam instrument. Finally,
our HK' data were collected using the QUIRC camera on the University
of Hawaii 2.2 m telescope.

Note (1): This is the output from the SExtractor FWHM-IMAGE measurement.
The FWHM is calculated in a different manner than the semimajor and
semiminor axes, which are outputs from the A-IMAGE and B-IMAGE
measurements. All three of these measurements were made on the
unsmoothed images with respect to centroids in the detection images
and have been scaled to arcseconds. A value of zero indicates that the
measurement could not be determined. For more information on these
parameters see Bertin & Arnouts (1996A&AS..117..393B 1996A&AS..117..393B).

--------------------------------------------------------------------------------
Note (1): Saturated pixels behave in a very nonlinear fashion on Suprime-Cam
and can drop in value after reaching the saturation limit. We adopted
these magnitude cuts by measuring the magnitude at which point sources
became non-Gaussian.
