RMSF -- Not wide enough for CLEAN & Doesn't adjust to account for flagging #47

Open AlecThomson opened 5 years ago

Currently, the output RMSF is the same width as the specified Faraday depth range. For CLEAN an RMSF of twice the FD range to be CLEANed is required.

Also, implementations such as RM-Tools "correctly deals with isolated clumps of NaN-flagged voxels within the data-cube (unlikely in interferometric cubes, but possible in single-dish cubes)". Specifically, if a NaN is detected, the channel is set to 0 and the weight is also set to zero. The ability to specify a weight per channel would be beneficial. Or, even better would be the output of an RMSF per pixel that correctly accounts for varying flagging per voxel.
