CFHTLS-T0007 photometric redshifts
October 8th 2012
This page provides information about publicly-available photometric redshifts in the Canada-France Hawaii Telescope Legacy survey wide fields. These photometric redshifts were computed using the TERAPIX-T0007 photometric catalogues.
These photometric redshifts were computed at Terapix and LAM using the TERAPIX-T0007 photometric catalogues. They have been calibrated using spectroscopic redshifts from the VVDS , zCOSMOS and VIPERS surveys obtained at the ESO-VLT, as well as DEEP2 obtained at the Keck.
The data can be retrieved from the following ftp repository :

Information about the catalogues
The input photometric catalogues are those the CFHTLS-T0007. Magnitudes in this catalogue were corrected for galactic extinction using the Schlegel et al (1998) dust maps.
Full information about the catalogues can be found in the release documentation in the ftp directory.
