Yes, I agree with you, but I think that in future we shall have more
record from couple or too arrays of cameras then we shall to do
this corrections for to have more reliable data: it's possible that,
as occur sometime today, satellites can to take all trajectory and
with more reliable data on infrared.
Best greetings.
