A problem of excess signal developed in the data from 17-22 Feb.
 It turned out to be caused from rain on a unshielded cable.        
 After wrapping the cable (1700, 22-Feb) the problem went away.
 Data for this period were corrected to subtract the excess signal.

 On days Feb 13 and 23, missing data (10 minute values) were replaced
 with extrapolated values to reconstruct the daily profile.
 On days Feb 10, 11, 12, Mar 2 and 8 too much data lost and reconstruction
 was not attempted.

 Note:  If interested, the raw daily light counts recorded at 10 minute
        intervals is available from the Data Management Office.
