Description:
The conditioning electronics box on the Electronics was was switched off for the two days 
in question.  It might have been bumped or something.  It was turned back on at the end 
of the day on July 3rd, 2007.  Do not use the data from July 2nd or July 3rd.
Suggestions: 
Don't use the data from these two days.
