Layout of the NISP FPA, orientated as looking towards the FPA from the sky and NISP optics. 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 towards the sky see Fig. A.2.
