Scientific paper

The Canada-France-Hawaii Telescope (CFHT) has recently commissined two facility infrared cameras for astronomical observations in the 1.0 to 2.5 micron region. These cameras use Near Infrared Camera and Multi-Object Spectrometer 3 (NICMOS3) 256 x 256 pixel arrays fabricated from Hg:Cd:Te. We report here on array performance and discuss two unique features of these arrays, namely corner glow and residual images. We have developed techniques for reducing corner glow and a method of clearing residual image charge. We discuss our techniques and their side effects.
