Bases: object

The piecewise-exponential interpolation strategy.

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

with

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