Hello I am doing LeedTOR analysis recently. But I get this low-frequency contrast image. I don’t know if there is something wrong with my detector or if I am doing something wrong.

I can’t be sure but it looks like this was done without a filter in place. Note the very bright center line and darker edges. Did you select the bowtie to be in the field? The non-uniformity of the base image is likely washing out the contrast here.
