J/ApJ/481/673     HDF flanking fields and related data        (Lowenthal+, 1997)

Keck spectroscopy of redshift z∼3 galaxies in the Hubble Deep Field. Lowenthal J.D., Koo D.C., Guzman R., Gallego J., Phillips A.C., Faber S.M., Vogt N.P., Illingworth G.D., Gronwall C. <Astrophys. J., 481, 673-688 (1997)> =1997ApJ...481..673L
ADC_Keywords: Surveys ; Galaxy catalogs ; Redshifts ; Photometry, HST Keywords: galaxies: distances and redshifts - galaxies: evolution - galaxies: starburst - surveys Description: File flanking.dat contains Unpublished Catalogue of Galaxies identified by the DEEP Team in the Flanking Fields. This is the source catalogue that Vogt et al. (1997ApJ...479L.121V), Phillips et al. (1997ApJ...489..543P), Guzman et al. (1997ApJ...489..559G), and Mendez & Guzman (1998A&A...333..106M) used to select objects. The photometry in this catalogue was carried out using circular apertures of 3 arcsec diameter, as described by Phillips et al. (1997ApJ...489..543P). These will present small differences (∼0.12mag, rms) relative to published values for the sample of 51 compact galaxies that were analysed by Phillips et al. (1997ApJ...489..543P) and Guzman et al. (1997ApJ...489..559G). This is because for the papers, the I(814) magnitudes were recalculated using elliptical apertures to 8 arcsec. The differences should only be significant in the case of galaxies with larger apparent sizes or with elongated shapes. File Summary:

Note (1): Fields as follows: 1 = ie, inner east field 2 = ne, northeast field 3 = oe, outer east field 4 = se, southeast field 5 = iw, inner west field 6 = nw, northwest field 7 = ow, outer west field 8 = sw, southwest field Note (2): RA and DE are in the same astrometric system defined by the position of objects in the HDF, as listed in version 1 of the catalogs provided by the HDF team. The positions listed here are internally consistent (rms<0.2arcsec). Note (3): Redshifts were assigned by matching the positions listed by A. Phillips in his redshift compilation within a 3" radius. Note (4): Half-light radii and surface brightnesses were derived from the curve of growth using circular apertures up to 3" diameter. Note that those values derived for large objects are most likely in error. No corrections for PSF were applied. Note (5): V(606) aperture magnitudes were measured in circular apertures with r=1.12arcsec (i.e., 2xPSF) from V(LRIS) images, and transformed to the HST F606 Vega system using HDF objects in common. Note (6): I(814) aperture magnitudes were measured in circular apertures with r=1.12arcsec from degraded HST images (using the PSF of the V(LRIS) image.
