the derivatives changed in some instances compared to the old
implementations. this patch updates them to the new versions.
thanks to [at]atgeirr for discovering this.
- satfuncStandard: Unscaled curves, using standard version of the
Gwseg model.
- satfuncEPSBase: Unscaled curves, but using the EPS version of
the Gwseg model. There are some differences between this and the
standard version of Gwseg for derivatives at critical saturations.
The scheme for calculating the derivatives should be discussed.
(Will file a separate issue on this.)
- satfuncEPS_A: Scaled curves. Scaling parameters specified via
SWL family.
- satfuncEPS_B: Scaled curves. Scaling parameters identical to _A
but this time specified via the ENPTVD table. Test currently
suspended due problems with eclipse-state.
- satfuncEPS_C: Scaled curves. Scaling parameters identical to _A
but this time specified via Norne-like syntax (EQUALS, COPY etc.).
