Waiting on FHD image.

The plan is to read in a Cotter uvfits with pyuvdata, then write out a new uvfits. Then run both the original and the new one through FHD and check that they're the same.

We do see differences in the two files, but they appear to be caused by floating point precision errors on the uvws (which are single precision in the Cotter files).
