Bimodal fields
--------------

We provide two transformations to obtain bimodal distributions:

* `arcsin <https://en.wikipedia.org/wiki/Arcsine_distribution>`__.
* `uquad <https://en.wikipedia.org/wiki/U-quadratic_distribution>`__.

Both transformations will preserve the mean and variance of the given field by default.

See: :any:`transform.normal_to_arcsin` and :any:`transform.normal_to_uquad`
