Subject:
SGP/MFRSR/E11 - Instrument failure
DataStreams:sgpmfrsrlangplotE11.c1, sgpmfrsrE11.b1, sgpmfrsrlangleyE11.c1
Description:
Beginning at 0552 UTC on 11/04, the MFRSR at E11 had frequent missing or erratic data. 
Corresponding to this, the head_temp readings and logger_volt readings were both flagged 
frequently (head_temp readings were erratic/noisy, and logger_volt readings were too high).  
Data quality was severely affected. Loggerboard replacement corrected the problem.
