Subject:	OLI/MPLCMASK/M1 - Reprocess: Instrument correction error
Affected Datastreams:	oli30smplcmask1zwangM1.c1
Description	Overlap and dead-time instrument corrections in the 30smplcmask1zwang VAP were not applied in the correct order. As a result, very high backscatter signals near 500 m can sometimes exceed the acceptable maximum signal for applying a dead-time correction. Regions, where the dead-time correction is not applied, appear as an artificial band or artifact. Cloud detection is not impacted by this issue.
Measurements	linear_depol_snr (Signal to noise ratio for the linear depolarization ratio) linear_depol_ratio (Linear depolarization ratio) backscatter_snr (Signal to noise ratio of backscatter) backscatter (Total attenuated backscatter)
