Subject:
TWP/MMCR/C2 - Instrument problem, Degraded hardware
DataStreams:twpmmcrpowC2.a1, twpmmcrmonC2.a1, twpmmcrmomentsC2.a1, twpmmcrcalC2.a1
Description:
The radar is down due to IEEE-488 bus problems.

There are sometimes several hours of data available in a given day during this period 
(immediately after a system reboot) but the large majority of the data are missing.
Suggestions: 
Avoid this period.
