SGP/MFRSR/E15 - Instrument noise
DataStreams:sgpmfrsrlangleyE15.c1, sgpmfrsrlangplotE15.c1, sgpmfrsrE15.b1, sgpmfrsrE15.a0
Description:
Intermittent negative spikes in some channels and the head temp.  A start date of 20050401 
has been identified, but the problem may precede that date.  20050401 is the first date 
with obvious negative spiking.  The instrument was on its way to failure, which it did 
just moments after this DQR ends.

Interested users should examine the data closely, and remove affected points. Look for 
spikes in some channels, but not in others at the same time.
