This is fine, and I agree it's likely to be faster, but I prefer to
pull the MIN() function call out of the IF statement. IDL doesn't
appear to guarantee the order of execution within statements, so it's
a bit risky to assume that the variable MAX will always be set
properly. [ Although, it does appear to be here. ]

Also, and this is a bit nit-picky, perhaps it's a bit dangerous to use
a variable named MAX, when a built-in function of the same name is
also present is a recipe for confusion, no?
