500 fb ^-1 SM Data Sample at Ecm=500 GeV

...

The first line indicates that a user-supplied function is used to simulate beamstrahlung. A copy of this function can
be found in ftp://ftp-lcd.slac.stanford.edu/ilc/ILC500/StandardModel/whizard-src/user.f90^{Image Removed}

The absolute value of USER_spectrum_mode determines which beamstrahlung spectrum is used, with the sign +/- indicating
electron/positron beam, respectively. For the 500 fb-1 SM data sample this absolute value is always 2, and corresponds
to the Guinea-Pig beamstrahlung data contained in the directory ftp://ftp-lcd.slac.stanford.edu/ilc/ILC500/StandardModel/guinea-pig/ilc_0500_may05_run05_seed06/^{Image Removed}
This spectrum represents the default ILC design for Ecm=500 GeV circa August 2005.
