Morning Cees and readers

Many thanks for your reply. Your program is even better than I originally
thought and I can see it replacing the one I use for LEO sats.

I wondered what the comment "maximum" meant on each line of your
scan prediction and I like the fact that it scans for the point of maximum
brightness - improves the chances of seeing a faint satellite.

I am still a little puzzled why you need to specify the altitude of the
satellite. You are using TLE's and either computing shadow entry or
exit points or maximum brightness so you must be using the altititude
given by the elements so why is there a need to specify the altitude?
(to be honest I am being a little lazy here as I am trying to avoid
having to use a prediction to get an idea of the altitude to enter in
the command line.

Yes I would prefer a prediction point a little before ingress or after 
egress
so as to make sure I get at least one or two positions before the
satellite disappears or after it re-appears.

Thanks once again for a very useful piece of software - wish I had your
mathematical ability but I know my limitations!

Cheers
Greg
