ePump (error PDF Updating Method Package)


UNDER CONSTRUCTION!!!

- Update the best-fit and Hessian Error PDFs given new experimental data.
- Optimize the Hessian Error PDFs for a particular set of observables.


  1. The source code can be obtained here: ePump_v20181001.
  2. Here is an application for making plots of PDFs: PDFigure. The author of this code is Tie-Jiun Hou, (tjhou@msu.edu).
  3. Please send questions or comments to schmidt@pa.msu.edu
