pre edgeΒΆ

Pre-edge subtraction and normalization:

  • fit a line of polynomial to the region below the edge

  • determine E0

  • fit a polynomial to the region above the edge

  • extrapolate the two curves to E0 to determine the edge

note: you can open a pop up window for computing mean or median E0 value from the dataset using the button at the right of the E0 entry line
