           reduction: no information
         coordinates: X and Y are the differences in position 
         between the Quaoar and the satellite           
    diff. refraction: no information (see in publications)

Comments.
The binary has been resolved at seven of these nine epochs, and the remaining
two provide upper limits 0.3  
For the two moments 1550.31485  and 1556.44075  the satellite
was not detected, it is assumed that the satellite image fell within
Quaoar’s core.

The Julian date of moment of observation is JD=2453000+T ,
the moment  T = 781.38031 is  14.02.2006
