2016	173.50	3.457	Plot, orbital elements and data Sixth Catalog of Orbits of Visual Binary Stars data. DateDate of the last observation used in the orbit calculation, if published. : 2015 \| GradeThe grade (to nearest integer), as previously discussed. : 5 PThe period (P), followed by code indicating units: "c" = centuries, "d" = days, "h" = hours, "m" = minutes, "y" = years. : 365.637500 y \| aThe semi-major axis (a), followed by code indicating units: "a" = arcseconds, "m" = milliarcseconds, "u" = microarcseconds. : 3.46130 a \| iThe inclination (i), in degrees. : 56.1610 \| ΩThe node (Omega), in degrees. An identified ascending node is indicated by an asterisk following the value. : 153.9540 \| 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. : 1903.662700 y eThe eccentricity (e). : 0.259850 \| WThe longitude of periastron (w), in degrees, reckoned from the node as listed. : 259.4700 \| EquinoxEquinox, if any, to which the node refers. : system note Orbit note
