But what if you don't know the standard magnitude, but the RCS area? In some TLE's you will see the estimated (not based on visual observations) standard magnitude. Where does that figure come from? Is it just a guess based on previous experience, or is there a formula(s) involved? ------------------------------ Jonathan T.
