Problematic nitrogen basis in examples #92

Open vanderhe opened 2 months ago

vanderhe commented 2 months ago

The one-center calculation of nitrogen, as defined in examples/mio/skdef.hsd, does currently not converge, seemingly due to numerical instabilities owing to an extremely large basis (MaxPowers=3).

According to my tests, this is the case since (at least) v0.2, i.e. before the mixer overhaul.
