Hi,
Holy mackerel, this really works; thanks a lot, guys. I played
around a little bit with the
suggestions by faulkner and hdante and pieced together the following

p1.communicate()
my_output.close()
I've never used that, though, please tell us if it worked.

plot the data using an
external program (psxy in GMT). The plotting program takes x-y
