Common instrumental view to the sky of the VIS (blue) and NISP (red) instruments. The footprint was generated from two simultaneously taken VIS and NISP images, astrometrically calibrated and registered to a common pixel grid. Small blue numbers refer to VIS, large red numbers to NISP detector IDs. Interchip gaps are evident. The VIS detectors have an additional thin horizontal gap (not shown here) from the charge-injection lines used to monitor radiation damage through charge-transfer inefficiency. The respective spatial and angular offsets between both instruments are ${52}_{\cdot }^{\mathrm{\prime }\mathrm{\prime }}5$ and $0_{\cdot }^{\circ }078$.
