Reprocess: Wrong calibration factor applied to NIP

From about 950721 to about 970204 (19:12 GMT) the wrong calibration
factor was applied to the NIP at site E10.  The calibration factor
that was used was 1.00E-06 Volts/(W m^2).  The correct calibration
factor is 8.338E-06 Volts/(W m^2).  Thus the calibrated NIP values
found in the netCDF files are too large by a factor of 8.338.

Divide the calibrated NIP values given in the netCDF files by 8.338.
