Subject:
OLI/RL/M1 - Photon counting and analog signals  contaminated with ambient and laser light
DataStreams:olirlM1.a0
Description:
A malfunction of the narrow-field-of-view (NFOV) "flipper" caused light to leak into the 
mode 0 measurement. The mode 0 measurement is used to characterize the response of the 
system in the absence of any light (i.e. its used to measure the noise). The measurement is 
done once per hour. During the period in question the mechanism that's used to block the 
aperture (flipper) for the NFOV channels malfunctioned.
A new flipper was installed on 2016-09-21.
