Sorry, I thought the discussion was about the XM sats, which is 
why I said they were circular.  You are right about it being a small 
figure 8.
   I also made the mistake of looking up the wrong Sirius 1.  20193 
is also called Sirius 1, and it is circular with a small inclination, 
however now I see I had the wrong. Sirius 1.

Sorry for the mistake.
