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

Hope this is the right thread for this question?
The SHERLOC imager is said to be a direct build to print version of the MAHLI imager on MSL. With MAHLI images the focus motor count is provided on the raw image server, using that count enables users to approximate the distance and scale of 'close-up' / 'in-focus' MAHLI images. The SHERLOC images returned so far don't appear to have a motor count on the raw image server (that I can find) Is the SHERLOC motor count provided on an image JSON feed somewhere? Any pointers would be appreciated, as I'd hope to check it's my use of the count using targets like the PIXL calibration target where its exact size is known. Then I can use it for scaling the geological targets in the future. TIA ![]() |

Is the SHERLOC motor count provided on an image JSON feed somewhere? Not yet, maybe someday. See post 89. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
