About the question of "fix deposit"

Dear all,

I have a question about velocity setting in "fix deposit "

fix 2 newatoms deposit 10000 1 500 12345 region disk near 2.0 vz -1.0 -0.8

In the statement above, vz is set to -1.0 -0.8. does it mean it randomly scaled between this range? or with uniform distribution? if it randomly choose, does it uniform random or Gaussian random ?

Thanks so much for your great help! Lu Xie

uniform random between vlo and vhi
