C idruplh : The identity of the current process,
C as given by the LPRUP codes.
C eventweightlh : The event weight:
C Equal to (total cross section)/(total generated)
C for the output of Pythia, Herwig, etc.
C alphaqedlh : QED coupling alpha_em.
C alphaqcdlh : QCD coupling alpha_s.
C scalelh(10) : Squared Scale Q of the event.
C......Defined for standard 2->1->2 or 2->2 process
C.......kinematics are p1 + p2 -> q1 + q2
C scalehl(1)= Q2 hard scale (used in PDF and couplings)
C scalehl(2)= Q2 scale of parton shower
C scalehl(3)= s-hat, invariant (p1+p2)**2
C scalehl(4)= t-hat, invariant (p1-q1)**2
C scalehl(5)= u-hat, invariant (p1-q2)**2
C scalehl(6)= squared transverse momentum of q1 (i.e., pt-hat**2)
C.......Additionally, for 2->3 processes, p1 + p2 -> q1 + q2 + q3
C scalehl(7)= squared transverse momentum of q2
C scalehl(8)= user defined, 0 by default
C scalehl(9)= user defined, 0 by default
C scalehl(10)= user defined, 0 by default
C spinlh(3,..) : spin information
C icolorflowlh(2,..) : (Anti-)Colour flow.
