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.)
