Background Endpoint Averaging at Start and End BEs
NO Averaging for this example:Â 0.00 eV
(One single point, at start and end BEs, was used to connect baseline endpoints)
Look at the upper red line, which produces a smaller peak area, and more error in atom% results.
This was connected by using only 1 endpoint.
The other red background (below) was connected by using endpoint averaging spread over a 0.5 eV range at both ends.
0.5 eV Range used to Averaging for this exampleÂ
(Average of 5 data points, at start and end BEs, was used to define and connect baseline endpoints)
Look at the lower red line. It produces a larger peak area. It produces a more accurate atom% result.
Two different Averaged Endpoints
We produced two different F (1s) peak areas for atom% quantitation.  Shirley Backgrounds were used for both integration. But the endpoints were different.
The difference is hard to see unless you zoom in on the baseline region, as shown below.

One (1s) peak area and two different Averaged Endpoints were compared for atom% quantitation by using different F (1s) peaks having different endpoints
