Platform/Measurement: All data
What level data: (raw,a0,a1,b1,c1 etc): All
What location was the data collected at: Central
Period of time in question
Begin Date 95/03/08 Time 20:33 (GMT)
End Date 95/03/08 Time 23:02 (GMT)
Data should be labeled:
___ questionable ___ All data fields affected
___ incorrect ___ Only some data fields affected
___ wrong calibration
___ others
Discussion of Problem:
The MFRSR head for sgpmsirosE13 was changed by the mentors. The old head, 917,
was removed for recalibration, and the new head, 921, was installed.
No data was acquired between 95/03/08 20:33-23:02.
The data logger PROM was upgraded from Version 12 to Version 13.
Other observations/measurements impacted by this problem:
The data logger clock lost 31 seconds per day after the PROM upgrade until
reset with a new clock constant at 95/03/16 05:33.
Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
