The worm-scraped patch 2 of the previous message, shaped like an ellipse twice as tall as it is wide, is inside the blue circle (A).  Can you see it? The mangled glyph must be mostly a (wrong) restoration.

The worm-scraped patch 1, that runs along the valley crease of the parchment, is inside the red polygon (B).  It visibly damaged glyphs on lines 2-4.  It is not clear to me which parts of those glyphs are original, which are correctly restored, and which are wrongly restored.

There may be a lot more damage in that clip. For instance, just to the right of the blue circle there is another rough patch, shaped like a down-pointing triangle, which may have erased glyphs on lines 2 and 3. 

In your (great!) website, the images with suffix 1 have light shining at an oblique angle from North relative to the page.  Images with sufix 2 have oblique light shining from South. The difference between these two images, each properly equalized, should show the N-S slope of the surface, and thus maybe show rough spots more clearly.

 (Images with suffix 0 have both lights on -- a waste of time, since the result should be the average of 1 and 2.  It would have been more useful to use instead a light from East or West.  Then one could use photometric stereo techniques to get a height map of the surface, with resolution of 1-2 pixels.)

All the best, --jorge
