Layout of the NISP FPA, orientated as looking towards the sky. Shown are the positions 11 to 44 of the SCS in the focal plane mosaic (see Table 3), the origin point and orientation of the physical R-MOSAIC coordinate system, as well as the pixel coordinate system for each of the SCA detectors. For the latter please note the 180° rotation between the upper and lower half of detectors. For a view from the sky towards the FPA see Fig. A.1. An internal definition of a position angle value of zero would rotate this view on the sky so that north is upwards and east is to the left.
