Subject:
TWP/CEIL/C1 - Compensation fiber
DataStreams:twpceilC1.b1
Description:
The VCEIL was reporting a "receiver optical cross-talk compensation is poor" warning. The 
window was cleaned and the instrument was power-cycled. The problem was corrected when 
the compensation fiber was replaced and ants were removed from communication connector.  
Cloud detection was impaired.
Suggestions: 
Data is suspect when status_flag = W.
