The first level is a full-field run using all WL and SL data on relatively low resolution, which then serves as a template for the run on the med-resolution regimes focussing on the area which is covered by the VLT and HST WL catalogue. This reconstruction is then again used as a template for the final reconstruction of the cluster core on high resolution and which is mostly dominated by the CL constraints. lowres: -750.0 -- 750.0; -750.0 -- 750.0 [x/y/in arcsec] around centre 60x60 [pixels] with 25 arcsec resolution per pixel medres: -50.0 -- 150.0; -50.0 -- 150.0 [x/y/in arcsec] around centre 16x16 pixels with 12.5 arcsec resolution per pixel highres: -50.0 -- 115.2; -50.0 -- 115.2 [x/y/in arcsec] around centre 20x20 pixel with 8.3 arcsec resolution per pixel Error maps info: Also provided are error maps for convergence, shear and magnification.

The maps show a simple 1 SD error in each pixel, as they are derived from the bootstraps using the full sample and not only certain quartiles, as discussed within the map maker teams. Bootstraps: Description: Because of the way SaWLens works and to keep runtime at acceptable levels, we produce bootstrap realisations for three different regimes of the cluster field separately. The mask files show masked pixels in the reconstructed field by a pixel value of "not 0" instead of 0 for unmasked pixels. The bootstraps were derived by bootstrap-resampling the input WL catalogues and by randomly sampling the allowed redshift range of SL features.
