# 0. REFRAIN from editing this file by hand! Some of the parame-     *
#    ters are not independent                                        *
#    (such as G_Fermi, alpha_em, sin(theta_W),MZ,MW) and serious     *
#    problems might be encountered (such as violation of unitarity   *
#    or gauge invariance).  Always use a calculator.                 *
#                                                                    *
# 1. alpha_S(MZ) has been used in the calculation of the parameters  *
#    but, for consistency, it will be reset by madgraph to the       *
#    value expected IF the pdfs for collisions with hadrons are      *
#    used. This value is KEPT by madgraph when no pdf are used       *
#    lpp(i)=0 .                                                      *
#                                                                    *
#  2. Values of the charm and bottom kinematic (pole) masses are     *
#     those used in the matrix elements and phase space UNLESS they  *
#     are set to ZERO from the start in the model (particles.dat)    *
#     This happens, for example,  when using 5-flavor QCD where      *
#     charm and bottom are treated as partons in the initial state   *
#     and a zero mass might be hardwired in the model definition.    *
#                                                                    *
