PR Summary
Fixes #5062. The bug was caused by conversion mistakes when converting from physical units to plot coordinates.
The sphere callback (and others) multiply input units by a factor, expressed in 1/length. When the input units depend on the Hubble factor (e.g., Mpc/h), the multiplication yields a value in units of
1/h
, so an extra conversion to remove theh
factor is required. This is what this PR does.PR Checklist
