  • Publishable Notes For Orbits Of Minor Planets

    Alphabetic notes that are associated with orbits are defined according to the scheme below:
      D  Double (or multiple) designation(s)
      E  Eccentricity assumed
      F  = D + E
    
    In residual blocks the following codes are used:
     ( ) Brackets surround the residuals of observations rejected
            from the solution
      Y  Observation published to precision of 0s.1 in R.A. and
            1" in Decl.
      X  Observation published to precision of < 1s in R.A. or
            < 0'.1 in Decl.
