No chance, there's no way I would run anything
but Java without first running the virus checker
on it and even then I try to use a backup machine.
Your VB programs have full access to my system so
there's no way to detect a trojan in it.

I am using the term in the same sense as Sekerin
and you.

Over observational periods, that's fairly reasoanble.
The path won't change much in the seconds to hours it
takes to record a spectrum in most cases.

Actually, no. There may be a lot of factors that
influence the speed but the final light curve and
spectrum only depend on the integrated effect of
the speed difference.

Please find out what "reference frame" means Henry,
I know what you meant but what you said is rubbish.

Close to stars they may vary but once they reach open
space the ISM is going to be fairly consistent. Any
significant concentrations will be detectable due to
the dimming and reddening they would cause.

You don't need to know the real distance, beyond a few
times the extinction distance no further change happens
to the curves because what you call the "time compression"
effect ceases. We are so far from even the nearest stars
that it is always the case.
