# `DISTRIBUTION, CUTOFFPZ = 0` does not imply cutoff infinity and produces infinite loop

### Summary

The documentation of `DISTRIBUTION, CUTOFFPZ = 0`

mentions an infinity cutoff, but this is currently not true.

### Steps to reproduce

set `DISTRIBUTION, CUTOFFPZ = 0`

###
*bug* behavior?

What is the current Infinite loop

###
*correct* behavior?

What is the expected According to the manual `CUTOFFPZ`

:

*Defines cutoff in p_{z} dimension in units of \sigma_{pz}. If CUTOFFPZ = 0 then actual cutoff is p_{z} is set to infinity.*

### Possible fixes

The following line in Distribution.cpp should be changed for cutoffP_m[2] in a similar way as x and y:

` allow = (xAndYOk && pxAndPyOk && std::abs(z) < cutoffR_m[2] && std::abs(pz) < cutoffP_m[2]);`

### Varia

For consistency I propose also to make `CUTOFFLONG=0`

an infinite cutoff.
