As with XAFS analysis, the slope of the pre-edge is extrapolated to the edge energy. The value of the spline through the above-edge data at the (above-)edge position is taken as the above-edge value. Therefore the XAS structure above the edge is fitted to a low-order piece-wise continuous polynomial.
