Animation of sol 4 OM test:

This animation puzzles me. What exactly> is being imaged?

I an guessing that some of the dark spots are dust on some protective plate between the OM and the samples, and some of the straight dark filaments with shadows are some unknown fibers caught on the other side of the plate.

But what are the small, bright raised blobs of material on the substrate -- especially what is the short rod shaped blob center left?

There appears to be a complex network of raised linear features ( not depressions ) all over the substrata.

What is this substrate -- and what does the expected image look like?

Sure would like to see an "official" version with explanation of these images.

Be warned that there are a lot of GIF color artifacts in the animation.

Again, Where are the OM raw images?

( Like Cato The Elder who ended all his speeches speeches with Carthago delenda est, I will end mine with "Where are the OM raw images"? )
