 Other parameters define, in particular, whether you turn the fragmentation and showers on or off. You can set them as you need. Importantly, one has to set the ''IGLU'' parameter corresponding to the TMD gluon density, used in the ''*.lhe'' file calculation. The TMD number can be found in the ''*.lhe'' file, it corresponds to the [[https://tmdlib.hepforge.org/doxy/html/pdfsets.html|TMDLib numbering scheme]]. PEGASUS uses the following of them (see [[pegasus:overview|Overview]]). The ''ICCF'' parameter should be defined according to the used TMD gluon distribution. Other parameters define, in particular, whether you turn the fragmentation and showers on or off.
