It will deliver 135 rows spatially and a full 256 pixels spectrally. Its first telescope implementation will be in late April at the 1.3-m. May. The major optical components have all been contracted out as well. The Cryogenic Optical Bench, a second generation IR camera emphasizing a great variety of spatial and spectral filtering modes, has been to the telescope most recently with a 256 x 256 SBRC InSb array. This instrument has had some difficulties, including a redesign of a portion of the optics to suppress ghosting.
Problems remaining are mostly in achieving acceptably precise control of mechanical moving parts.
We expect it to be available for general use in spring 1994. As a side benefit, we now know the latitude, longitude, and elevation of the 2.1-m to within a few meters courtesy of NASA and the GPS satellite network.
