MSTW PDFs : supplementary plots for eigenvector PDF sets

Here we provide supplementary plots documenting the eigenvector PDF sets, and the dynamic determination of the tolerance, for each of the LO, NLO and NNLO fits. See Section 6 of arXiv:0901.0002 for more explanation.

  • Change in global chi-squared versus distance (t) along each eigenvector:
    LO, NLO, NNLO.
  • Change in chi-squared for each data set when moving along each eigenvector:
    LO, NLO, NNLO.
  • Change in global chi-squared for which data sets are satisfied within their 90% C.L. or 68% C.L. limits:
    LO, NLO, NNLO.
  • Tolerance for each eigenvector direction determined dynamically:
    LO, NLO, NNLO.
  • Absolute contribution to the 68% C.L. uncertainty on the input PDFs from a single eigenvector:
    LO, NLO, NNLO.
  • Fractional contribution to the 68% C.L. uncertainty on the input PDFs from a single eigenvector:
    LO, NLO, NNLO.
  • Absolute contribution to the 90% C.L. uncertainty on the input PDFs from a single eigenvector:
    LO, NLO, NNLO.
  • Fractional contribution to the 90% C.L. uncertainty on the input PDFs from a single eigenvector:
    LO, NLO, NNLO.
