# Hewett and Wild 2010, MNRAS, 405, 2302: "Improved redshifts for SDSS quasar spectra"
# Redshifts for the sky-residual-corrected DR7-release spectra of the
# extended quasar catalogue generated as described in Hewett and Wild 2010.
# The sample of 107194 objects includes all
# the quasars from Schneider et al. (2010, AJ, 139, 2360) and an additional sample
# of ~1200 objects, most of which possess redshift z>0.4 but fail the
# Schneider et al. "broad emission line" definition.
# The material is effectively an extended version of Table 4 from the Hewett & Wild 2010 
# paper for the larger sample of DR7 quasars using the DR7 Legacy Release spectra.
# Col.  1: SDSS object name
# Col.  2: Right ascension J2000 (decimal degrees)
# Col.  3: Declination     J2000 (decimal degrees)
# Col.  4: Redshift estimate
# Col.  5: Redshift error [actual z_err rather than dz/(1+z) in the MNRAS Table 4 DR6 version]
# Col.  6: FIRST Detection status (1 detected; -1 not-detected; 0 outside FIRST footprint)
# Col.  7: Alternate redshift for objects with Col. 6 code = 1 or 0 and
#          cross-correlation redshift estimate > 1.10
# Col.  8: Redshift estimation method code (1 [OIII]; 2 [OII];
#          3 MgII_cc; 4 CIII]_cc; 5 CIV_cc; 6 extra_cc; 7 Schneider et al. 2010)
# Col.  9: SDSS spectroscopic plate
# Col. 10: SDSS MJD of spectroscopic observation
# Col. 11: SDSS spectroscopic fibre number
# Col. 12: Composite spectrum flag (0 single spectrum used as specified via Cols. 9/10/11,
