The WHIZARD Monte Carlo version 1.40 is used for parton generation. For processes with (without) an on-shell Higgs boson in the final state the Higgs mass is assumed to be 120 GeV (2000 GeV). The Makefile and build log files for this implementation of WHIZARD can be found in ftp://ftp-lcd.slac.stanford.edu/ilc2/whizdata/ILC500/doc/whizard-v1r4p0 .
