This is a catalogue of photometric redshifts of galaxies in the Stripe 82
obtained when morphology (galaxy size, ellipticity, Sérsic index, and
surface brightness) are included in training on galaxy samples from the
SDSS and the CFHT Stripe-82 Survey (CS82). Our redshifts yield a 68th
percentile error of 0.058(1 + z), and a outlier fraction of 5.2 per cent.

The distributions :math:`P(z)` used to estimate z_phot and z_morph are
available as FITS binary tables from `pz_phot`_ (1.4 GB) and `pz_morph`_
(0.8 GB), respectively.
.. _pz_phot: /\schema/q/cone/static/cs82_pz_morph.fits.gz
.. _pz_morph: /\schema/q/cone/static/cs82_pz_phot.fits.gz
The data in the \schema.main table is also available as a FITS binary
table: `phz.fits`_ (0.7 GB).
