Resolve / fix AWH likely inconsistent units
According to the discussion in !2361, AWH seems to use degrees as the units for awh1-dim1-start/end, while the documentation says radians, and if a cover-diameter is used, those units are not converted (meaning radians).
Exact steps to reproduce
For developers: Why is this important?
Inconsistent units for start/end vs. cover-diameter is a recipe for bugs, and we need the documentation to reflect the implementation.
Given that the standard pull package uses degrees everywhere, and AWH is apparently already partly doing that, by far the cleanest solution seems to standardize on that, even if it means cover-diameter will be reinterpreted.
