HYDICE system performance: an update

The HYDICE instrument began flying at the beginning of 1995. Since then a large body of data has been acquired--on the ground, from characterization flights and from operational missions. In combination with laboratory data, this has been used to conduct an evaluation of the full system. Overall, performance has matched design predictions quite closely, both with respect to technical specifications and operational characteristics. Some anomalies have been identified. Their causes, the impact they have on data quality and methods of correcting them have been assessed. This paper reports on these findings, provides an updated status of the system, and identifies possible hardware upgrades.
