OLI/MET/M1 - Noisy (and missing) CMH data

The chilled mirror hygrometer data became noisy after self-checks during this period. Data 
are missing between 10/16 and 10/21 for service and calibration checks. The instrument 
was returned to service following calibration checks and minor connection repairs.
