Description: | The down_short_hemisp (PSP), up_long_hemisp (PIR) and down_long_hemisp_shaded (PIR) start
dropping out 12/18 and eventually go missing at 19:05 GMT on 1/03/08. Problem is diurnal
but inconsistent. PM found a loose power cable on the mux and repaired on 1/16 1745.
Missing data are not recoverable. However, during the initial period of infrequent missing
data from 12/18 to 1/3/08 the user can potentially rely on DQ flags to exclude poor data
instead of the entire data set. |
