Abstract:
Detection and photometry of sources in the Un, G, {R}, and Ks bands
in a 9x9 arcmin2 region of the sky, centered on the Hubble Deep
Field, are described. The data permit construction of complete
photometric catalogs to roughly Un=25, G=26, {R}=25.5, Ks=20
mag and significant photometric measurements somewhat fainter. Galaxy
catalogs selected in the {R} and Ks bands are presented, containing
3607 and 488 sources in field areas of 74.8 and 59.4arcmin2, to
{R}=25.5 and Ks=20mag.
Description:
For visual data, Un=0.53F300W+0.47F450W-0.29mag,
G=0.83F450W+0.18F606W-0.07mag, and {R}=0.46F606W+0.54F814W-0.02mag
images taken with the COSMIC camera (Kells et al.,
1998PASP..110.1487K 1998PASP..110.1487K) at the prime focus of the 200 inch Hale Telescope
at the Palomar Observatory were used. The Un, G, and {R} filters are
described in Steidel & Hamilton (1993AJ....105.2017S 1993AJ....105.2017S); briefly, they
have effective wavelengths of 3570, 4830, and 6930Å, FWHM
bandpasses of 700, 1200, and 1500Å, and zero-magnitude flux
densities of roughly 1550, 3890, and 2750Jy. These magnitudes are Vega
relative, not AB. For near-infrared data, an 8' diameter circular
region centered on the HDF was imaged on 1997 March 19 - 21 using a
Ks filter with a near-infrared camera (Jarrett et al., 1994) mounted
at the prime focus of the 200 inch Hale Telescope. The Ks filter has
an effective wavelength of 2.15µm, a FWHM bandpass of 0.3µm,
and a zero-magnitude flux density of roughly 708Jy.
