Subsections
For these models, just include your settings to $RUNMC/proj/ini''
and recompile the project from ``proj''. In addition to this,
you can use steering cards in your current directory.
Examples of the steering cards are in ``example/steer/(MC model)'' for each MC model.
Note: settings defined in ``proj/ini'' are set at the very end, i. e. your parameters
defined in the steering cards can be overwritten via files in ``proj/ini''.
For this model, you need a steering card and a file with
unintegrated gluon densities. Unintegrated densities can be found in
http://www-h1.desy.de/~jung/cascade. You should copy one of it
to your current directory and rename it to ``ccfm.dat''.
One file with example unintegrated PDF is in the ``main/mcarlo/cascade-12/steer'' directory.
RunMC contains example steering cards for several processes in ``main/mcarlo/cascade-12/steer''.
You should copy one steering card to your current directory and rename it to ``cascade.cards''.
The file ``cascade.cards'' should be in the same directory where you execute
``runmc''.
This model is not supported by the author, therefore, the PHOJET model was
implemented as it is, with a minimal coding necessary for RunMC.
The cards
files for initialisations, located in ``example/steer/PHOJET'', are not standard
and are different from other Monte Carlo models. Because of this reason,
it is impossible to edit these steering cards using RunMC GUI.
This model also requires input PDF file, ``fitpar.dat'' (located in
``main/mcarlo/phojet/files'').
In addition, there is a rather different concept to fill histograms.
In case when PHOJET steering cards are used, RunMC first fills
a temporary binary file ``runmc.tmp'' with events, and only then it start
to read it and fill histograms. Thus, one may notice some delay at the
very beginning of the run, but this compensated by a very fast histogram
filling. Make sure that you have enough disk space (50k events usually require
60M for HERA experiment).
