NICI Detectors

NICI is equipped with two Aladdin III InSb detectors, one for each science channel. During commissioning, the detailed characteristics of each detector will be determined and provided here. The table below provides known or expected characteristics, the latter based on "typical" performance of Aladdin III detectors.
