I see the same results on my machine, so I don't think you are doing
anything wrong.  However, this package isn't part of scipy, and your
question looks to be of a field-specific nature, so it will be better
answered by the authors of coords themselves (some of them might be on
this list).

Best way to draw their attention is probably to file a ticket at
