Subject:
TWP/AERI/C2 - Data Loss due to Communication Problem
DataStreams:twpaerisummaryC2.b1, twpaeriengineerC2.b1, twpaerirawC2.00, twpaerich1C2.b1,
twpaerich2C2.b1
Description:
The spectrometer was periodically unable to transfer data to the computer. When this 
occurred, the data was deleted and lost as new data filled the spectrometer's memory. All 
existing data in this time period is good. However, much data is missing. For example, half 
of channel 1 and three-quarters of channel 2 may be missing. The DSP card was failing 
intermittantly and the problem was resolved when the card was replaced.
Suggestions: 
Users can safely use any data that exists but missing data can NOT be retrieved
