Contents of the GOODS-N-All Table
The GOODS-N-All tables provide a compendium of redshifts in the
HST/ACS imaging field from a variety of sources, including the the
Team Keck
Redshift Survey and the Cowie et al.
survey. The table is available in several formats, all of which have identical content
as described below.

Description |
| 1 |
ra |
double |
degrees |
Right Ascension derived from ACS catalog(J2000) |
| 2 |
dec |
double |

Declination derived from ACS catalog(J2000) |
| 3 |
bmag |

mag |
Magnitude in b passband from GOODS team ACS photometry
(see note 1) |
| 4 |
vmag |
real |
mag |
Magnitude in v passband from GOODS team ACS photometry
(see note 1) |
| 5 |
imag |
real |
mag |
Magnitude in i passband from GOODS team ACS photometry
(see note 1) |
| 6 |
zmag |
real |
mag |
Magnitude in z passband from GOODS team ACS photometry
(see note 1) |
| 7 |
z |
real |
|
Adopted Redshift (see note 2) |
| 8 |
zflag |
integer |
|
Flag whether spectrum was acquired with DEIMOS. Value
is 1 if the spectrum is based on a DEIMOS observation,
otherwise zero. DEIMOS redshifts should be more accurate
(sigma of 60 km/s) than the LRIS based redshifts (180 km/s). |
| 9 |
z_uhdmos |
real |
|
Redshift measured by UH/IfA team using Keck+DEIMOS |
| 10 |
z_uhlris |
real |
|
Redshift measured by UH/IfA team using Keck+LRIS |
| 11 |
z_tkrs |
real |
|
Redshift measured by Team Keck using Keck+DEIMOS |
| 12 |
z_cohen |
real |
|
Redshift measured by Judy Cohen et al. using Keck+LRIS |
| 13 |
z_lick |
real |
|
Redshift measured by Lick team using Keck+LRIS |
| 14 |
z_dawson |
real |
|
Redshift measured by Dawson et al. using Keck+LRIS |
| 15 |
z_steidel |
real |
|
Redshift measured by Steidel et al. using Keck+LRIS |
| 15 |
z_steidel |
real |
|
Redshift measured by others teams using Keck+LRIS |
Notes:
-
ACS magnitudes are not measured within comparable apertures
and hence may not be used for computing appropriate colors.
-
Where there are multiple redshifts the DEIMOS
value has been adopted (adopting Hawaii first
then TKRS unless there is a disagreement which
has been resolved in favor of a particular
redshift). After that we have chosen the
Hawaii LRIS redshift, the Caltech redshift,
the Lick redshift, or one of the remaining
redshifts in this order of priority. The
choice of ordering in both cases is somewhat arbitrary.
Note that in all redshift columns, a value of
-1 indicates no measure and -2 indicates a star.
