Thanks,

where did you get that info? I don't doubt your response, it's just that I would like more detailed information
on how scan_entity works, since I wrote this little "tool" to show the scan cone...I'd like for it to be accurate.

Edit:
Actually, I've updated my little tool since that last image was taken...can you look at the following
link (scroll to the bottom) and tell me if the scan cone reprentations look right? ...if you know
