-C...New numbering scheme and upgrade for LHAPDF v2.1
-C...by Dimitri Bourilkov and Mike Whalley
-C...
-C...For more information, or when you cite this interface, currently
-C...the official reference is:
-C...D.Bourilkov, "Study of Parton Density Function Uncertainties with
-C...LHAPDF and PYTHIA at LHC", hep-ph/0305126.
-C...
-C...The official LHAPDF page is:
-C...
-C... http://durpdg.dur.ac.uk/lhapdf/index.html
-C...
-C...The interface contains four subroutines (similar to PDFLIB).
-C...It can be used seamlessly by Monte Carlo generators
-C...interfaced to PDFLIB or in stand-alone mode.
-C...
-C... For initialization (called once)
-C...
-C... PDFSET(PARM,VALUE)
-C...
-C... For the proton/pion structure functions
-C...
-C... STRUCTM(X,Q,UPV,DNV,USEA,DSEA,STR,CHM,BOT,TOP,GLU)
-C...
-C... For the photon structure functions
-C...
-C... STRUCTP(X,Q2,P2,IP2,UPV,DNV,USEA,DSEA,STR,CHM,BOT,TOP,GLU)
-C...
-C... For statistics ON structure functions (under/over-flows)
-C...
-C... PDFSTA
-C...
-C...This interface can be invoked in 3 ways depending
-C...on the value of PARM(1) provided by the user when
-C...calling PDFSET(PARM,VALUE):
-C...
-C... For PYTHIA: PARM(1).EQ.'NPTYPE'
-C... (this is set automatically by PYTHIA)
-C...
-C... For HERWIG: PARM(1).EQ.'HWLHAPDF'
-C... (set by the USER e.g. in the main program like this:
-C... AUTPDF(1) = 'HWLHAPDF'
-C... AUTPDF(2) = 'HWLHAPDF' )
-C...
-C... For Stand-alone: PARM(1).EQ.'DEFAULT'
-C... (can be used for PDF studies or when interfacing
-C... new generators)
-C...
-C...The LHAPDF set/member is selected depending on the value of:
-C...
-C... PYTHIA: ABS(MSTP(51)) - proton
-C... ABS(MSTP(53)) - pion
-C... ABS(MSTP(55)) - photon
-C...
-C... HERWIG: ABS(INT(VALUE(1)))
-C...
-C... STAND-ALONE: ABS(INT(VALUE(1)))
-C...
-C...
-C... CONTROL switches:
-C... ==================
-C...
-C... THE LOCATION OF THE LHAPDF LIBRARY HAS TO BE SPECIFIED
-C... AS DESCRIBED BELOW (the rest is optional)
-C...
-C... if the user does nothing, sensible defaults
-C... are active; to change the behaviour, the corresponding
-C... values of LHAPARM() should be set to the values given below
-C...
-C... Location of the LHAPDF library of PDFs (pathname):
-C... uses common block /LHAPDFC/
-C...
-C... If the user does nothing => default = subdir PDFsets of the
-C... current directory (can be real subdir
-C... OR a soft link to the real location)
-C... If the user sets LHAPATH => supplied by the USER who defines the
-C... path in common block COMMON/LHAPDFC/LHAPATH
-C... BEFORE calling PDFSET
-C...
-C... Other controls:
-C... ===============
-C... use common block /LHACONTROL/
-C...
-C... Collect statistics on under/over-flow requests for PDFs
-C... outside their validity ranges in X and Q**2
-C... (call PDFSTA at end of run to print it out)
-C...
-C... LHAPARM(16).EQ.'NOSTAT' => No statistics (faster)
-C... LHAPARM(16).NE.'NOSTAT' => Default: collect statistics
-C...
-C... Option to use the values for the strong coupling alpha_s
-C... as computed in LHAPDF in the MC generator
-C... (to ensure uniformity between the MC generator and the PDF set)
-C... WARNING: implemented ONLY for PYTHIA in LHAPDFv4
-C...
-C... LHAPARM(17).EQ.'LHAPDF' => Use alpha_s from LHAPDF
-C... LHAPARM(17).NE.'LHAPDF' => Default (same as LHAPDF v1/v3)
-C...
-C... Extrapolation of PDFs outside LHAPDF validity range given by
-C... [Xmin,Xmax] and [Q2min,Q2max]; DEFAULT => PDFs "frozen" at the
-C... boundaries
-C...
-C... LHAPARM(18).EQ.'EXTRAPOLATE' => Extrapolate PDFs on OWN RISK
-C... WARNING: Crazy values can be returned
-C...
-C... Printout of initialization information in PDFSET (by default)
-C...
-C... LHAPARM(19).EQ.'SILENT' => No printout (silent mode)
-C... LHAPARM(19).EQ.'LOWKEY' => Print 5 times (almost silent mode)
-C...
-C...
-C...v5.0 06-Oct-2005 Major change to allow multiset-initializations
-C...v4.0 28-Apr-2005 PDFSTA routine; option to use Alfa_s from LHAPDF
-C...v4.0 21-Mar-2005 Photon/pion/new p PDFs, updated for LHAPDF v4
-C...v3.1 26-Apr-2004 New numbering scheme, updated for LHAPDF v2/v3
