J/AJ/131/2383    Photometry and spectroscopy in the HDF-S    (Glazebrook+, 2006)

Anglo-Australian Telescope imaging and microslit spectroscopy in the southern Hubble Deep Field. Glazebrook K., Verma A., Boyle B., Oliver S., Mann R.G., Monbleau D. <Astron. J., 131, 2383-2393 (2006)> =2006AJ....131.2383G
ADC_Keywords: Photometry ; Redshifts ; Galaxy catalogs Keywords: catalogs - galaxies: evolution - instrumentation: spectrographs - surveys Abstract: We present a deep photometric (B- and R-band) catalog and an associated spectroscopic redshift survey conducted in the vicinity of the Hubble Deep Field-South. The spectroscopy yields 53 extragalactic redshifts in the range 0<z<1.4, substantially increasing the body of spectroscopic work in this field to over 200 objects. The targets are selected from deep Anglo-Australian Telescope prime-focus images complete to R<24, and the spectroscopy is 50% complete at R=23. Description: Images in B and R were taken with the Anglo-Australian Telescope (AAT) prime-focus CCD camera (0.391"/pixel) in 1999 May at two pointings containing the Wide Field Planetary Camera (WFPC; AAT-WF) and Space Telescope Imaging Spectrograph (STIS; AAT-ST) fields. The spectroscopic observations were made with the AAT Low Dispersion Survey Spectrograph, and carried out over the nights of 1998 October 13-16 at the AAT. File Summary:

Note (1): NULL entries throughout this table denote missing data primarily due to the B band data being less deep than the R band but also slightly different depth and coverage at the edge of the fields and differences in extraction due to the presence of strong straylight features. This table is not cleaned for sources lying in masked areas (i.e. in vignetted regions or along sites where stray light is strong) but the mask flag is included in the table. Note (2): Parent image of the detection, defined as follows: WF = AAT-WFPC2 field; ST = AAT-STIS field; WS = Overlap region; WMS = Overlap region but masked in one of the fields. Note (4): NULL means not detected. Note (6): Photometric condition defined as follows: PH = photometric conditions (WF-B, WF-R, ST-R data); NP = non-photometric conditions where calibration using common sources detected in the photometric (WF-B) and non-photometric (ST-B) lying in the overlap region has been used. Note (7): Generally <8 is reliable.

Note (2): In preliminary version of photometric catalog used for selection. Note (3): Quality system, defined as follows: 4 = Denotes a dead-certain redshift (>99% confidence) 3 = Is "quite certain" (∼80% confidence) 2 = Is a possible identification (∼50% confidence) 1 = Is a single emission line redshift assumed to be [OII] (which is the best a priori guess, given the likely redshift range at R<24 and wavelength converage) 0 = Represents no identification
