Zenmuse XT2 Camera model - can't edit dimensions

Hi - I’m trying to make a temperature map from the thermal r.jpg images acquired with a Zenmuse XT2 camera, where the focal length was 13 mm and the images are 640 x 512. There is just one camera model that shows up and it is for 336 x 256 pixels and the image size is not editable, despite trying. My problem might be that the images don’t have enough overlap, but it seems like the wrong camera model is a potential source of error as well. I will (try to) upload the log file and one image.

Thanks for any tips!
