Informations.
       relative to: the primary
    eference frame: astrometric ICRF 
   centre of frame: topocentric 
  epoch of equinox: J2000 
        time scale: UTC 
         reduction: no information
       coordinates: X, Y (secondary relative to primary) 
  diff. refraction: no information 
          receptor:

Comments. The relative coordinates are mentioned as Delta(R.A.), Delta(Decl.). 
          All data is from Gemini except the October
          14th, 2007 discovery data from Subaru and 
          the September 20th, 2008 observations from HST by Noll 
          et al. (2009). The m is the difference in magnitude
          between the two components. On February 9, 2010 the
          individual binary components were not resolved and 
          thus zero was chosen for the offset.                                                       
Format. 
                                      
 1. Year of the moment of observation 
 2. Month of the moment of observation  
 3. Day of the moment of observation with decimals
 4. X - relative right ascension, arcsec
 5. SigX - the error of X (1sigma uncertainties), arcsec
 6. Y - relative declination, arcsec 
 7. SigY - the error of Y, arcsec
 8. m - relative magnitude (99.99 means no data)
 9. Sig m - the error of m (99.99 means no data)
10. Nobs - code of observatory
