Abstract:
The Bright Ages Survey is a K-band-selected redshift survey over six
separate fields with UBVRIzJHK imaging covering a total of
75.6arcmin2 and reaching K=20-20.5. Two fields have deep HST
imaging, while all are centered on possible overdensities in the
range. Here we report photometric redshifts and spectroscopy for this
sample, which has been described in Paper I (Colbert et al.,
2006ApJ...638..603C 2006ApJ...638..603C).
Description:
All spectroscopy was done at the W.M. Keck Observatory using the Low
Resolution Imaging Spectrometer over eight nights from 2000 March
through 2003 August.
