Background Subtraction Methods
						Linear - Simple line drawn between two points, intensity (i.e. Area) is portion of the peak above this line Shirley - Background intensity at a point is proportional to the total peak area above the background and to higher binding energy (scattered electrons adding to the peak rise, unscattered electrons giving a flat background) Tougaard - Extends this idea further by calculation of the actual background function due to scattering Consideration of Linear and Shirley Backgrounds
