Combined vignetting-corrected EPIC exposure map of the SMC main field and additional outer fields, as used for the catalogue. The survey observation provide a homogeneous coverage in addition to the deep field around 1E0102.2-7219. EPIC-MOS1 and -MOS2 exposure is weighted by a factor of 0.4 relative to EPIC-pn to account for the lower effective area.
