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
