/** @page pdfsets PDF sets Official LHAPDF 6.1 PDF sets: currently 360 available, of which 347 are validated. See http://www.hepforge.org/archive/lhapdf/pdfsets/6.1 for data downloads. All sets behave very closely to their LHAPDF v5 equivalents, usually within 1 part in 1000 across x,Q space, sometimes with larger very localised deviations at the edges of the x,Q grid or on flavour thresholds: these should not be physically important. See http://lhapdf.hepforge.org/validationpdfs/ for a full set of validation plots for each set's central member. In the table, green rows indicate sets which have been officially approved for LHAPDF6 by their authors. Red rows indicate those which have not yet been so approved. Unvalidated sets may still be used and have generally been seen to behave faithfully to their LHAPDF5 equivalents (see above), but please take care.
