Fragment 6 volume(s) discontinuity around layer 7975

[jrudolph]

Two of the fragment 6 volumes show a discontinuity around layer 7975 that also shows in the rendered segment

This affects at least volumes 20231121152933 (3.24um/53keV) and 20231201120546 (3.24um/70keV) while 20231201112849 does not seem affected.

In the RGB overlay the discontinuity looks like this:

with everything below the red line having a blue hue (20231201112849) due to that volume not having the discontinuity at that place. Would be interesting to understand how that happened, though this might be more of an erratum to file somewhere.
