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.

Miralles,Norbert Purger,Samuel Schmidt,Jack Singal +25 more
TL;DR: The PHoto-z Accuracy Testing Program (PHAT) as mentioned in this paper is an international initiative to test and compare different methods of photo-z estimation, and the test data sets are publicly available and can be used to compare new, upcoming methods to established ones and help in guiding future photoz method development.

TL;DR: In this paper, the stellar-to-halo mass ratio (SHMR) of the CFHT Legacy Survey (CFHT-LSTS) data was used to study the evolution of the galaxy population over cosmic time.
Journal ArticleDOI
Group-finding with photometric redshifts: the photo-z probability peaks algorithm
TL;DR: The photo-z probability peaks (P3) algorithm as mentioned in this paper is optimized for locating small galaxy groups using photometric redshift data by searching for peaks in the signal-to-noise ratio (S/N) of the local overdensity of galaxies in a 3D grid.
