Visual display of the masks developed for VIPERS, inside a 1 deg² region of the survey. The new bright-star mask is marked by the magenta circles and cross patterns, while the original mask distributed by Terapix, based on the four-point star template, is shown in green; orange polygons are drawn around selected extended sources. The quadrants that make up the VIPERS pointings are plotted in red. In the background is the CFHTLS T0006 χ² image of the field 020631-050800 produced by Terapix. Note the significant gain in usable sky obtained with the new VIPERS-specific mask.
