############################################################################## # Catalog of 984 objects with I_814 < 23.74 in the Flanking Fields # # around the Hubble Deep Field (R. Guzman, April 12, 1997) # # Minor fixes, added Journal reference to z (C. Willmer, 19 February 1999) # ############################################################################## # Notes: # # 1) RA and DEC are in the same astrometric system defined by the positions # # 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 < 0.2 arcsec). # # 2) Redshifts were assigned by matching the positions listed by A. Phillips # # in his redshift compilation within a 3" radius. # 3) I_814 total magnitudes were derived using DAOPHOT (in Vega system). # # 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. # # 5) V_606 aperture magnitudes were measured in circular apertures with # # r=1.12 arcsec (i.e., 2xPSF) from V_LRIS images, and transformed to # # the HST F606 Vega system using HDF objects in common. # # 6) I_814 aperture magnitudes were measured in circular apertures with # # r=1.12 arcsec from degraded HST images (using the PSF of the V_LRIS # # image. # # 7) INDEF values in redshifts, aperture magnitudes and colors, mean no # # measurements available. # ############################################################################## id char %20s 20 # Object ID: (field)(chip)_(xcoor)_(ycoor) x real %7.2f # X-coor (pixels) y real %7.2f # Y-coor (pixels) field int %1d # Field ID: 1=ie, 2=ne, 3=oe, 4=se # # 5=iw, 6=nw, 7=ow, 8=sw RA double %12.2h # Right ascension (2000) DEC double %12.2h # Declination (2000) z real %7.3f # Redshift mt814 real %7.2f # I_814 total magnitude lre real %7.3f # Half-light radius (in log of arcsec) c real %7.2f # Concentration index sbe real %7.2f # Average surface brigthness within Re ma606 real %7.2f # V_606 aperture magnitude ma814 real %7.2f # I_814 aperture magnitude v_i real %7.2f # V_606 - I_814 colors zref char %15s 15 # Redshift Reference
