Platform/Measurement: All data
	What level data: (raw,a0,a1,b1,c1 etc): All

    What location was the data collected at: Ringwood

    Period of time in question
 	Begin Date  95/03/08   Time   17:14    (GMT)
 	End Date    95/03/08   Time   22:59    (GMT)

 Data should be labeled:
 ___  questionable                      ___  All data fields affected
 _X_  incorrect                         ___  Only some data fields affected
 ___  wrong calibration
 ___  others 

 Discussion of Problem:

The MFRSR head for sgpmsirosE15 was changed by the mentors. The old head, 924,
was removed for recalibration, and the new head, 230, was installed.
No data was acquired between 95/03/08 17:14-18:39.
The data logger PROM was upgraded from Version 12 to Version 13.
Data logger flags in the comm program were incorrect during the period
95/03/08 18:39-22:59 and all data during that interval are no good.

Other observations/measurements impacted by this problem:

The data logger clock lost 17 seconds per day after the PROM upgrade until
reset with a new clock constant at 95/03/16 05:18.

Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
