Description:
The Deep Extragalactic Evolutionary Probe (DEEP) is a multi-year
program which uses the twin 10m Keck Telescopes and the Hubble
Space Telescope (HST) to conduct a truly large-scale survey of
distant, faint, field galaxies. The broad scientific goals include:
the formation and evolution of galaxies, the origin of large-scale
structure, the nature of the dark matter, and the geometry of the
Universe. This project is led by the Lick Observatory at University
of California (UC) Santa Cruz, in collaboration with UC Berkeley,
University of Hawaii (UH) Manoa, Johns Hopkins University, University
of Chicago and California Institute of Technology.
The photometric data were taken with the CFH12K camera on the
3.6-meter Canada-France-Hawai'i Telescope. Each DEEP2 field is covered
by multiple CFHT/CFH12K pointings with each pointing numbered within
its respective

Note (1): the 2 leftmost digits of the object number is made of the
field and pointing numbers.
Note (2): 1pixel = 0.207arcsec
Note (3): The BADFLAG code is computed as Bflag+6*Rflag+36*Iflag from a
flag in the range 0-5 for each filter, meaning the following:
0 = good pixel
1 = no data available
2 = excessively bright object centered here
3 = saturated pixel at object location
4 = identified as a suspect pixel in the dilation process by brightmask.pro
5 = within 10-pixel buffer of a bad pixel (of type 1-4)
Note (4): Values between 0 and 1 give the probability that a compact object
is a galaxy. Values Pgal>1 indicates an extended source and definitely
a galaxy; negative values indicate point sources.
