of course you should read 370 !
for some reason listserv replace the degree symbol with a zero.
(when i send an email containing the degree symbol to myself, it come back OK, not as a zero)
sometimes, international communication is not that easy.
Hopefully, its was not highly strategical data, some wars have begun for less...
If you read the provided link in my initial post, you will read it correctly.
