Left: image enhanced with a Gaussian blur and a histogram equalization, as discussed in Martínez-Delgado et al. (2008). The paths indicate the positions of the missing parts of the streams east of the galaxy; this is the iconic part of the double loop system. The black box corresponds to the region where a 100% coverage has been achieved. Right: weight map of the stack in a logarithmic representation. White corresponds to a 100% coverage, i.e., the area with 7.2-h exposure in total, black to 0%.
