@bsipocz - a useful trick if you want to just completely remove changes to `test_api_ape5.py`: make a local copy of `test_sky_coord.py`, use ``git rebase --hard 5b6b3d6`` to go back to the commit before the test, copy `test_sky_coord.py` over, and make a new commit.

An alternative is to use ``git revert  35b153c``, which will make a *new* commit that just undoes everything in ``35b153c`` (which presumably means the file will be left in its original form)
