SPECTROSCOPY OF THE HDF-N ACS GOODS FIELD -- TABLES

OBSERVATIONS OF THE HAWAII HDF-N FIELD

Spectroscopy of the ACS GOODS Area of The HDF-N

DATA TABLES

The Hawaii table includes sources observed by our group with either the LRIS or Deimos spectrographs lying in the ACS-GOODS region and satisfying the magnitude limits z' < 24, R < 24.5 or B < 25, where the magnitudes are the ground-based total magnitudes from Capak et al. 2004. This is table 1 in Cowie et al. 2004. The table is ordered by R magnitude. The columns are RA(2000) and Dec(2000) in decimal degrees, the z', R and B magnitudes. and then redshift. In this ASCII version of the table z=-2.000 denotes a star and z=0.000 denotes an object which was observed but not identified.

ACS SUMMARY TABLE

The ACS Summary table is a summary of all the redshift information available on sources in the ACS catalog with z < 24, i < 24.3, v < 24.5 or b < 25 where the magnitudes are isophotal magnitudes from the ACS catalog. All the sources in the ACS catalog satisfying these criteria are listed whether or not there is a redshift.

Columns 1:6
The coordinates and magnitudes are taken from the ACS catalog. The RA and Dec (2000) are given in decimal degrees and the magnitudes are the isophotal magnitudes in the 4 color bands. All objects with z<24,i<24.3,v<24.5 or b<25 are included and the table is ordered by increasing v magnitude.

Column 7 gives the adopted redshift. Where there are multiple redshift 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.

Column 8 is a flag which is 1 if the spectrum is based on a DEIMOS observation. These redshifts should be more accurate (sigma of 60 km/s) than the LRIS based redshifts (180km/s).

Columns 9 and 10 show the Hawaii redshifts given in Cowie et al. (2004) reference 1. Some of these have previously appeared in references 2 through 5. Column 9 shows DEIMOS based redshifts and column 10 LRIS based redshifts.

Column 11 shows the TKRS redshift of Wirth et al. (2004) reference 7.

Column 12 shows redshifts from the Caltech group based on LRIS data. These are taken from references,2,3 and 8.

Column 13 shows redshifts from the Lick group. These are taken from references 9 and 10.

Column 14 shows redshifts from the Dawson et al. (2001) reference 11.

Column 15 shows redshifts from Steidel et al. (2003) reference 12.

Column 16 shows other redshift measurements taken from references 13,14,15 and 16.
