time would also become 
a Gaussian with the same width as the <i>z</i> one (times the 
velocity of the beams, which we expect is close to unity). For flexibility
we have not enforced any such relation, however.

The collision time is restricted to be in the range 
<i>|t| &lt; sigma_t * maxDevTime</i>.
