Only
the electrons passing through the selected energy slit contribute to
these
images.

In
the case of the three-window method

1) one window is positioned at
the region of the edge onset of the element in question
2) The two
other windows are positioned at energies below the edge
onset.

Images acquired at these two windows are used to calculate
the background image, this means, the background contribution to the
image recorded at the edge onset. Subtraction of the former from the
latter produces the elemental distribution map. The three-window method
may be applied when the spectral region below the edge is not distorted
by the presence of other elements thus allowing a good background
fitting.
