Jan 23 at 16:00 comment added planetmaker Also relevant: agupubs.onlinelibrary.wiley.com/doi/10.1029/2020JE006728 agupubs.onlinelibrary.wiley.com/doi/10.1029/2023EA002863 See also ui.adsabs.harvard.edu/abs/2018LPI....49.2443R/abstract from 2018 where he talks about bugs in earlier versions for ellipse fitting... so check whether the claim regarding orientation holds at all.
Jan 23 at 15:21 comment added planetmaker A non-circular crater is by definition elliptical. The cited paper states in its abstract "More elliptical craters are found than past work, orientation of D ≥ 10 km craters are random, and many spatial density trends are discussed". Did you read the discussion and maybe some of the relevant references (or papers referencing this)? You certainly did. It would be nice, if you could summarize for us your findings and insights to see where you stand, and to get us to a point to not pointlessly re-iterate what is known and to find a good place to start answering. It's an interesting question!
