Billinge Group and community contributors.
This code was derived from the first PDFFIT program by Thomas Proffen. The sources were converted to C++ by Jacques Bloch and then extensively hacked, extended and purged from most glaring bugs by Chris Farrow and Pavol Juhas. This code is currently maintained as part of the DiffPy project to create python modules for structure investigations from diffraction data.
The DiffPy team is located in the Billinge-group at the Applied Physics and Applied Mathematics Department of the Columbia University in New York. Previous significant contributors to this code were
Pavol Juhas, Chris Farrow, Jacques Bloch, Wenduo Zhou
Please see the github contributions and the header of each source file for a detailed list of contributors. This is an open-source project and we hope and expect that the list of contributors will expand with time. Many thanks to all current and future contributors!

DiffPy was initiated as part of the Distributed Data Analysis of Neutron Scattering Experiments (DANSE) project, funded by the National Science Foundation under grant DMR-0520547.

We are truly grateful to all the people who have contributed, in all different ways, to this project: Thomas Proffen, Xiangyun Qiu, Pete Peterson and Jacques Bloch, previous Billinge-group members whose contributions to the codes are living well beyond their affiliation with the group; The hard working DANSE group at Caltech, University of Maryland, Iowa State and University of Tennessee, especially Brent Fultz for doggedly putting DANSE all together and Michael Aivazis, and the indomitable Mike McKerns for their design input and MM's gargantuan excel spreadsheets; The former members of the Billinge-group members, especially HyunJeong Kim and Ahmad Masadeh for enthusiastic testing and feature requests; Last but not least, our long suffering family members, and the whole coffee and tea industries at large, without whom none of this would have been possible.
