Description (last modified by Vickie Lynch) (diff)
Art Shultz found error in profile integration. Integral should be Peak - (peak width)/ (background width) * Background. Error should be sqrt(Peak + ((peak width)/ (background width))^2 * Background).

Test is passed.
It is better to add the corrected formulas in wiki.
