Perseverance Imagery, technical discussion of processing, cameras, etc. Options

[Greenish]

Putting this here, for reference as the payload of the JSON feed link for Perseverence raws (see source in other thread here)

Looks like there's a ton of good data in addition to just the (PNG! Bayer color separated!) images

This is for the first image shown on the page at the moment.

Here's hoping that one of you skilled characters can make good use...

Does anybody know this plate's purpose?



Here are some other pictures:

It's a 'Bellypan' that protected the Adaptive Caching Assembly (ACA) since launch, but especially during the final part of EDL...

Surface operations on Mars require the Sample Handling Assembly (SHA) to extend approximately 200 mm (~8 inches) below the Rover’s bellypan. Therefore, an ejectable belly-pan was implemented directly below the Adaptive Caching Assembly (ACA) volume, which was released after landing to provide the SHA with an unobstructed volume to extend into during operations. Surface features are then assessed via Rover imaging prior to SHA motion to prevent contact with potential obstacles below the Rover.
