The gallows intrusion, the baseline jumps and multipass

[Anton]

An unfortunate circumstance came to my mind. The fact is that many folios are not flattened in scanning, so in fact that would influence the observed baseline and may give false impression of the change in its trends. Probably that would not affect the jumps, but there will be false positives as to changes in slope.
