Correct for Dynamic Dark
The pixels of the CCD detector are thermally sensitive, which causes a small
dark current, even without light exposure. To get an approximation of this
dark current, the signal of the first 14 optical black pixels of the CCD-detector
can be taken and subtracted from the raw scope data. This will happen if the
correct for dynamic dark option is enabled. As these 14 pixels have the same
thermal behavior as the active pixels, the correction is dynamic.
Percentage of the new dark value pixels that has to be used. E.G., a percentage
of 100 means only new dark values are used. A percentage of 10 means that 10
percent of the new dark values is used and 90 percent of the old values is used
for drift correction.
