| One component is SB; the RV range in the combined light is 45 km/s. | ||
| Branham (2005) uses this system illustrate a method for calculating | Bnh2005 | |
| orbital elements. His elements are not included in the catalog, as | ||
| he considers them only an example. | ||
| Combined spectroscopic/visual solution by Branham (2007). Additional | Bnh2007 | |
| elements: V0 = -13.339 +/- 0.010 km/sec, K1 = -6.921 +/- 0.022 km/sec, | ||
| K2 = -9.061 +/- 0.020 km/sec, parallax = 0".014 +/- 0".008, | ||
| fractional mass = 0.433 +/- 0.002. | ||
