Detailed Description

Stores additional information about PDFs.

This is an example of event attribute used to store PDF-related information

Note: Input parton flavour codes id1 & id2 are expected to obey the PDG code conventions, especially g = 21.; The contents of pdf1 and pdf2 are expected to be x*f(x). The LHAPDF set ids are the entries in the first column of https://lhapdf.hepforge.org/pdfsets.html
