4.1.6 Single particles

In particular for detector performance studies, it is convenient to be able to generate single particle within a range of angles and momenta. To do so, add the card

into the cradle, and add the cards PMIN, PMAX (range in momentum), THMIN, THMAX (range in $\theta$) and PHMIN, PHMAX (range in $\phi$) into the steering file. Also select the kind of particle to generate by adding the card KPART, giving the JETSET particle code. The variables will then be generated from independent rectangular distributions for each of the variables within the limits specified.

If the minimal value is not given for one of the variables, that variable will be fixed at the value given for the maximal value.
