Anomalously low cFAR for interpretable map

Consider a case like this: [image] [image] [image] [image] [image] Nominally ~3 Å, SCF* marginal but ok (0.8), map is interpretable, but cFAR is abysmal (0.02). I’ve seen this before for other datasets, too, early-ish in processing. Is cFAR being thrown off by a couple of directions with a lot of junk, or what? In any case, it seems like in these cases, cFAR is not the best metric for judging anisotropy. Has anyone else noticed similar results? My impression is that a low cFAR is possib…
