Known problem
for ver 1.6:
-
* nLw at saturation channels (490, 565, 666nm..) in V1.6
Level-2 NL (algorithm: OTSK1A) are sometimes invalid. This is caused by
bug on masking for saturation pixels.
-
-
Known problem
for ver 2.1:
-
* nLw at saturation channels (490, 565, 666, 680, 710nm..)
in V2.1x Level-3 NL (algorithm: OTSK1A/OSBin/OTBin) are sometimes
invalid. This is caused by summing scheme in the Leve-3
Binning.
