Red Cluster Sequence Lensing Survey (RCSLenS) catalogue ======================================================= These catalogues were queried on the [RCSLenS catalog query page](http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/community/rcslens/query.html). As the survey is quite large (more that 70 million sources) we first queried only the position of all the sources to generate a MOC (`RCSLenS_MOC.fits`) for all the survey. The we compared it to HELP coverage: | Field |Coverage| |------------------|-------:| | COSMOS| 0.0| | GAMA-15| 0.0| | XMM-LSS| 0.0| | Bootes| 0.0| | CDFS-SWIRE| 0.0| | ELAIS-N1| 100.0| | GAMA-12|

processed by `filterAndTag.sh` to keep only the sources on HELP coverage. ## Description of the columns taken from the output VO-table | Name | Description |
