ESCADT: A FORTRAN code for computing the positions and areas of Xray photoelectron spectral peaks
Abstract
The program ESCAD which uses least squares derived convoluting numbers to smooth and differentiate Xray photoelectron spectra is described. Peak maxima are located by finding zero crossings of the first derivative and refined using a cubic polynomial fitting procedure. Background points are located using the product of the absolute value of the first derivative and the smoothed ordinate value. Peak areas, using both linear and scattered electron backgrounds, are computed. Spectra are corrected for changes in instrument sensitivity and energy calibration with gold standard data retrieved from a disk file.
