Hi, I am trying to make a k-factor calibration with the method exactly as
Aaron discribed in the following few lines.

in light of Doug's message I wonder if a cut on track impact angle upon
the cell would help the situation. I think Aaron is right that large
impact angle tracks are not that common.
