Bases: object

The piecewise-linear interpolation strategy.

$${\sigma }_{sb}(\overrightarrow{\alpha })={\sigma }_{sb}^0(\overrightarrow{\alpha })+\underset{\text{deltas to calculate}}{\underbrace{\sum _{p\in \text{Syst}}{I}_{\text{lin.}}({\alpha }_p;{\sigma }_{sb}^0,{\sigma }_{psb}^{+},{\sigma }_{psb}^{-})}}$$

with

$$\begin{array}{r}{I}_{\text{lin.}}(\alpha ;I^0,I^{+},I^{-})=\{\begin{array}{l}\alpha (I^{+}-I^0)\alpha \ge 0\\ \alpha (I^0-I^{-})\alpha <0\end{array}\end{array}$$
