NSA/AERI/C1 - Instrument off-line due to detector failure
DataStreams:nsaaerisummaryC1.a1, nsaaeriengineerC1.a1, nsaaerich1C1.a1, nsaaerich2C1.a1, nsaaeriC1.00
Description:
Detector failure caused the instrument to be shut down until a new detector could be 
obtained and calibrated. There was no data generated during this period. The new detector was 
installed on 020731 and the instument was on-line at 23:00 GMT.
