Hello Sadek,
I just got the codes, thanks, as I told you my interest in with the DST
geometry so if you don't mind I wold like to have the other tools.
I plan to export the data ona DST station, since STIR doesn't yet
recognise DST geometry. I could work with Kris on that one but I don't
know how much of programming it will require.

Regards
Theodore
