[Wien] Persisting LOPW and LAPW1 errors

[Laurence Marks]

As Martin Kroeker said, you have a positional error and "x patchsymm"
thinks that your z-position should be 0.83333333 (i.e. 5/6). I
strongly suggest that most beginners check their structures using this
utility as it frequently finds small errors.

This may or may not solve the problem. If it does not you need to
provide more information about the parameters, e.g. RKMAX, num_k.
