[amsat-bb] true tle

[N. Mahdinejad]

Dears.
Merry Christmas.  I wish all of you have happy holidays.
 I have question about true tle of amsat satellites.
There is one set of TLE in celestrak and one in each satellite webpage
in amsat . those are different from in clestrak.
Which of these TLE are true that I can use in unitrak for tracking?
My tracking predictions in following two pages are different. I don’t know why?

http://www.amsat.org/amsatnew/satellites/satInfo.php?satID=116&retURL=/satellites/status.php

 Any help would be gratefully appreciated.
Best Regards.
