Sixth Catalog of Orbits of Visual Binary Stars data.

 DateDate of the last observation used in the orbit calculation, if published. : 1970 |  GradeThe grade (to nearest integer), as previously discussed. : 4 |

 PThe period (P), followed by code indicating units: "c" = centuries, "d" = days, "h" = hours, "m" = minutes, "y" = years. : 975.000000 y |  aThe semi-major axis (a), followed by code indicating units: "a" = arcseconds, "m" = milliarcseconds, "u" = microarcseconds. : 16.72500 a |  iThe inclination (i), in degrees. : 21.0000 |  ΩThe node (Omega), in degrees. An identified ascending node is indicated by an asterisk following the value. : 173.8000 |  TThe time of periastron passage (T), followed by code indicating units: "d" = Julian date, with first two digits truncated (i.e., JD-2400000), "m" = modified Julian date (JD-2400000.5), "y" = fractional Besselian year. : 2260.000000 y
 eThe eccentricity (e). : 0.280000 |  WThe longitude of periastron (w), in degrees, reckoned from the node as listed. : 44.0000 |  EquinoxEquinox, if any, to which the node refers. : 44.0000
