Revised SWIRE photometric redshifts
  We have revised the SWIRE Photometric Redshift Catalogue to take account of
new optical photometry in several of the SWIRE areas, and incorporating 2MASS
and UKIDSS near infrared data. Aperture matching is an important issue for
combining near infrared and optical data, and we have explored a number of
methods of doing this. The increased number of photometric bands available for
the redshift solution results in improvements both in the rms error and,
especially, in the outlier rate.
  We have also found that incorporating the dust torus emission into the QSO
templates improves the performance for QSO redshift estimation. Our revised
redshift catalogue contains over 1 million extragalactic objects, of which
26288 are QSOs.
