RCSLenS: The Red Cluster Sequence Lensing Survey
  We present the Red-sequence Cluster Lensing Survey (RCSLenS), an application
of the methods developed for the Canada France Hawaii Telescope Lensing Survey
(CFHTLenS) to the ~785deg$^2$, multi-band imaging data of the Red-sequence
Cluster Survey 2 (RCS2). This project represents the largest public,
sub-arcsecond seeing, multi-band survey to date that is suited for weak
gravitational lensing measurements. With a careful assessment of systematic
errors in shape measurements and photometric redshifts we extend the use of
this data set to allow cross-correlation analyses between weak lensing
observables and other data sets. We describe the imaging data, the data
reduction, masking, multi-colour photometry, photometric redshifts, shape
measurements, tests for systematic errors, and a blinding scheme to allow for
more objective measurements. In total we analyse 761 pointings with r-band
coverage, which constitutes our lensing sample. Residual large-scale B-mode
systematics prevent the use of this shear catalogue for cosmic shear science.
The effective number density of lensing sources over an unmasked area of
571.7deg$^2$ and down to a magnitude limit of r~24.5 is 8.1 galaxies per
arcmin$^2$ (weighted: 5.5 arcmin$^{-2}$) distributed over 14 patches on the
sky. Photometric redshifts based on 4-band griz data are available for 513
pointings covering an unmasked area of 383.5 deg$^2$ We present weak lensing
mass reconstructions of some example clusters as well as the full survey
representing the largest areas that have been mapped in this way. All our data
products are publicly available through CADC at
  http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/community/rcslens/query.html
  in a format very similar to the CFHTLenS data release.
