I see - yes in that case it is confusing.  However, in our case, we only
set the coordinates parameter in the code, not in the parameter file, so
this does not affect us.

Oh I see.  That's ok then :)  By the way, I think there is an
inconsistency between CarpetTracker and CarpetRegrid2.  Probably some
patches didn't get pushed regarding these parameters and grid scalars.
I think we discussed this ages ago but I never followed it up.
