Did you try to look at the manual?

as well as publication

It is about size of bunch in e^+, e^- collision.

In e^+, e^- collision.we have e^+, e^ interaction with leads to
photon radiation and decreasing of electron energy. So called ISR effect
which is
important for CERN LEP experiment. CalcHEP contains ISR distribution
function for it.

For next generation of e^+, e^ colliders one also has to take into
account bunch-butch
interaction. But may current realization implemented in CalcHEP it is
not good enough to e^+, e^ machines that
are developed now.
