Subject:
NSA/MMCR/C1 - Calibration Instability
DataStreams:nsammcrspecmomC1.a0, nsammcrmomC1.00
Description:
During this period the calibration of the MMCR varied significantly as monitored by the 
daily calibration values.  Stable operation resumed after a system reboot.
Suggestions: 
Do not use the data.
