AAO HDF-South Redshift Survey

Using the LDSS++ spectrograph  the AAO has undertaken a public domain redshift survey in the Hubble Deep Field South. Targets were selected from deep AAT Prime Focus Imaging to R<24 over a 9 arcmin x 3 arcmin field. 12 hours of exposure was taken in the novel  LDSS++ microslit/object-sky mode in October 1998. See the November and January 1998 AAO Newsletters for more information about the LDSS++ instrument.
 

The Redshifts

Table of redshifts vs object ID in photometric catalog. Please reference as Glazebrook et al. (2006) AJ in press , 2006 (AJ) for any use and further details.

The redshift histogram shows an interesting spike at z=0.58 which probably corresponds to a foreground cluster. 225 R<24 sources were observed spectroscopically at once. Spectral identifications go as deep as R=24, though the completenss is rather low at the limit due to an aperture-seeing mismatch. 
 
Magnitude range Completeness
R=23-24 18%
R<24 38%
R<23 46%
R<22 63%
R<21 80%

The spectra are available for download. Again please reference as above.

The Photometric Catalog

The final photometric catalog made from the (overlapping) AAT Prime Focus images of the STIS and WFPC2 fields is available. This is briefly described in the Glazebrook et al. paper and more fully in this Supplemental Appendix.

The  AAT prime focus images of the WFPC2 and STIS fields are available here, together with photometric and astrometric calibration information.
