Hello Jan!
I try again, sorry my bad explanation.
There are two images from 8a and 12 channels of the same region (exactly both of the same dimension), geographically identical.
Both have evident linking line from neighbore detecktor sets. But this “link” lines lie not on the same place at images. There is about 15 pixels distance one line from another. So on one image we may have cloud and on another clear due this difference in binding data form detector sets.
You may overlap images and see this (I try to show with screen shot)
Alexey
