AUTOBK

Automated Background Removal for XAFS Data

autobk was written with the guidance and encouragement of Edward A. Stern at the University of Washington. The idea for the main algorithm used in autobk (that is, adjusting the background until the low-frequency components of the resulting XAFS match those of a model calculation) was first suggested to me by Yizhak Yacoby. With great help from Peteris Livins, Ed Stern, and Yizhak Yacoby, autobk evolved from this algorithm, the application of information theory to XAFS analysis, and the desire for an automated way to reliably separate XAFS signal and background with as little input from the user as possible. I also thank Daniel Haskel, Maoxu Qian, John Rehr, Bruce Ravel, Steve Zabinsky and Yanjun Zhang for many useful suggestions.
