The software of some instruments uses the sum function, while others use the product function, so both functions are available in XPSPEAK. Calculation of the asymmetrical function using the Gaussian-Lorentzian product function was too difficult to implement. A few minor adjustments The addition of the Asymmetrical Peak Function required the peak function to be changed from the Gaussian-Lorentzian product function to the Gaussian-Lorentzian sum function.

Three additional file formats for importing data Some other minor graphical features were added The Export to Clipboard function was added as requested by a user Removed all the run-time errors that were reported Version 3.0 The major change in Version 3.0 is the addition of Newton’s Method for optimisation Newton’s method can greatly reduce the optimisation time for multiple region peak fitting. He also found other features that could be put into the program. Version 2.0 After the first version and Version 2.0, many people emailed Dr Kwok and gave additional suggestions. A better way to locate a point at a noise baseline for the Shirley background calculations įit different XPS regions at the same time Then he added the dreamed features into the program, e.g. Once this program was finished, he found that the program could be easily converted to a peak fitting program. Most of the information in this users guide has come directly from the readme.doc file, automatically installed with XPSPEAK4.1įirst Version In 1994, Dr Kwok wrote a program that converted the Kratos XPS spectral files to ASCII data. During that time, he dreamed of many features in the XPS peak fitting software that could help obtain more information from the XPS peaks and reduce processing time. Introduction Raymond Kwok, the author of XPSPEAK had spent >1000 hours on XPS peak fitting when he was a graduate student.
