Subject:
TWP/RL/C3 - Invalid depolarization channel data
DataStreams:twp10rlprofdep1turnC3.c0, twprlC3.a0, twprlprofmerge1turnC3.c0
Description:
The depolarization channel was not working properly during the period in question due to a 
failure of the high voltage power supply for the PMT.
Suggestions: 
Do not use data from the VAPs listed above during the effected period.
