TL;DR: In this paper, the authors present data products from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS) data set and demonstrate that their data meet necessary requirements to fully exploit the survey for weak gravitational lensing analyses in connection with photometric redshift studies.

CFHTLenS: Improving the quality of photometric redshifts with precision photometry
Hendrik Hildebrandt,T. Erben,Konrad Kuijken,L. van Waerbeke,Catherine Heymans,Jean Coupon,J. Benjamin,Christopher Bonnett,Liping Fu,Henk Hoekstra,Thomas D. Kitching,Yannick Mellier,Lance Miller,Malin Velander,Malin Velander,Michael J. Hudson,Michael J. Hudson,Barnaby Rowe,Tim Schrabback,Tim Schrabback,Elisabetta Semboloni,Narciso Benítez +21 more
TL;DR: In this article, the results of various approaches to measure accurate colours and photometric redshifts (photo-z) from wide-field imaging data are presented and different ways of correcting these effects are discussed and the resulting photo-z accuracies are quantified by comparing the photo-Z to large spectroscopic redshift data sets.

TL;DR: In this paper, the relation between dark matter halo mass and the baryonic content of their host galaxies, quantified through galaxy luminosit y and stellar mass, was investigated using 154deg 2 of Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS) lensing and photometric data, obtained from the CFHT Legacy Survey.
