I am attaching the code. I'm sorry, I am lacking the domain knowledge to make sense of it. Just one more remark: [] < 0.0 is always False, regardless of the contents of the list > Another question how do I get an integer value for p_za / 2 .

As you dig deeper the tutor mailing list may not be the best place to ask -- numpy has a dedicated mailing list of its own. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
