We report the results of a cosmic shear survey using the 4.2-m William Herschel Telescope on La Palma, to a depth of R = 25.8 (z ≈ 0.8), over 4 deg^2. The shear correlation functions are measured on scales from 1 to 15 arcmin, and are used to constrain cosmological parameters. We ensure that our measurements are free from instrumental systematic effects by performing a series of tests, including a decomposition of the signal into E- and B-modes. We also reanalyse the data independently, using… Expand
