MMHT Parton Distribution Functions

Here we provide the standalone interface code and grids for the Martin, Motylinski, Harland-Lang, Thorne (MMHT) 2014 LO, NLO and NNLO PDFs described in arXiv:1412.3989. These supersede the older MSTW 2008 PDFs, described in arXiv:0901.0002, and are superseded by the newer MSHT20 PDFs, described in arXiv:2012.04684.
