1. MK Equinox Meeting March 2008 Cassegrain upgrades UIST Controller upgrade: EDICT replaced by ARC Improved performance in all modes; Full-array readout in thermal bands 1kx 1k 4-point mosaic M’ (4.8 microns) Original readout method Saturated toward centre of array 1kx 1k 4-point mosaic M’ (4.8 microns) Row-reset readout No saturation More headroom, so Improved sensitivity BEFOREAFTER
