Just curious, has anyone gone spelunking in the Magellan SAR EDR (raw) dataset?

https://pds-imaging.jpl.nasa.gov/data/magellan/edr/

Looks like a set of 9-track mag tapes were copied to CD-ROMs for preservation,
and at some point the CD files were put online in PDS.

In starting to look at it, I realized that lack of knowledge of
mag tape volume/label/file/record structure and terminology may impede
younger explorers of this dataset.

That does indeed apply to the putative lava flow, but the change in the 2 km-wide caldera is, I think, incontestable.

Hmm. Well, I don't know. Google for "SAR layover". I worked on Magellan just enough to be very skeptical of changes in SAR data acquired with much different geometries. I would hope that the reviewers knew more about it than I do.
