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

The black margins on the Mastcam-Z frames are a bit of a pain to remove manually. I do this to permit stitching in MS-ICE without leaving shadows at some of the the seams.
Does anyone here know how I could use GIMP to process a batch at one session? Grateful for any advice |

In the Processing Options > cropping section. You can experiment with the offset and crop width fields. To preview, just click on the Test Options button. |
