For each event in a derived stdhep file the variable IDRUPLH from the common block HEPEV4 is used to identify the process. (See the
description of the IDRUPLH variable in the introduction above.)
Derived stdhep files

with randomized final states.
Derived stdhep files representing all SM processes at Ecm=250 GeV can be found at have been produced where different final states appear randomly:

Each directory listed above contains files inv_ab_stdhep_files_XXX_ecmEEE_80L_30R and inv_ab_stdhep_files_XXX_ecmEEE_80R_30L which describe the stdhep files used to build the associated derived files (for example ftp://ftp-lcd.slac.stanford.edu/ilc/ILC250/Large_Stdhep_SM/inv_ab_stdhep_files_Large_Stdhep_SM_ecm250_80L_30R).
The fields in the ..._inv_ab_stdhep_files are:

Defining your own derived stdhep files.
...
If you want your own derived file please fill in your version of a whizdata.in file and email to timb@slac.stanford.edu . At a minimum we will return a text file containing a list of the stdhep files to be read out. If there is sufficient ftp space we will also produce the derived file. Examples of the readout text files for the whizdata.in sample files metioned above can be found at ftp://ftp-lcd.slac.stanford.edu/ilc/ILC500/StandardModel/aa_bb_example_inv_ab_stdhep_files and
ftp://ftp-lcd.slac.stanford.edu/ilc/ILC500/StandardModel/qqlv_example_inv_ab_stdhep_files . The fields in the ..._example_inv_ab_stdhep_files are:

Whizard 1.40 has no gluon emission by default, leading to potentially incorrect multiplicity distributions.
