The trick with Monte Carlo analysis is to generate a properly randomized set of
test particles with the correct characteristics. There was some discussion a
while back about the properties of the random number generators in IDL. You
might check out www.dejanews.com, for example

Other than that, Monte Carlo is a fairly straightforward process. IDL may not
be the best language to implement it in, though, because of all the looping
you'll probably need to do.
