I think I'll be adding some bits and pieces related to You are not allowed to view links. Register or Login to view. MSI's here. I do occasionally run linear regressions on this or that feature, just to understand what it could be.
There is a tiny o-like loop (or part of a loop) in a EVA p (which belongs to EVA 130 composite) roughly at the middle of the page. From the visible light TIFF it's hard to tell whether this is just a spot or an actual pen stroke. I've checked the following registry of extended characters: You are not allowed to view links. Register or Login to view. and EVA 130 doesn't have this loop there.
To me the loop looks a bit more yellow than the normal ink and appears similar to the color of various spots on the page.
The verso of the folio has a painted leaf at the same location, so this doesn't look like a see-through of some text from the back of the page.
I've extracted the cropped portion of this area from individual MSI images, here's the result:
This doesn't seem to be normal ink, at least some of the images that clearly show the ink part have no traces of this small feature. On the other hand, it does look like a clearly defined feature. I tried to identify other parts of the folio that have similar spectrum (similar presence/absence profile across the whole set of images). The following image has all areas with similar profile highlighted in red.
It doesn't look like any other red areas show anything of interest. There is a red circle above EVA 'rod' to the bottom right, corresponding to a spot on the page, however it appears incidental. On the individual MSI images this is just a blurred square-like blob:
Considering all this, it does look possible that someone put a tiny circle or semicircle on that EVA p, maybe using a different kind of ink or paint.
