Nature of problem:
All theoretical calculations of cross sections involving the hadronic structure of the incoming particles, i.e. protons, pions or photons, use the parton density at a given longitudinal momentum X of the parton and at a given momentum transfer Q**2. There is a variety of parametrisations available. But each of them has its own structure for input and/or output.

Solution method:
Collection of all available parton density parametrisations and application in an identical format for all of them, regardless of the author's convention or of the particle type.
