Yes, that is the place. In principle it should be easy to fix, and maybe it is...or maybe it isn't. It will certainly have to do with transforms, and using the right one the right way in the right place. > > Also, why would a new kwarg be necessary?

The new kwarg could be "pad_units", as a modifier for the pad kwarg. Or something like a "padpoints" kwarg could be introduced as an overlapping replacement. Or we could just break the API and hope it doesn't cause too much trouble. I am not sure what the right approach is in this case. I'm also not sure whether this is the only place where a "pad" value is still in poorly-chosen units. There was another such case that we fixed quite a long time ago.
