# Nearby stars and star orbits out to 25 light years, supplementary
|
||
# to Celestia's stars.dat.
|
||
|
||
# Data are mainly derived from the RECONS survey tabulation at
|
||
# http://joy.chara.gsu.edu/RECONS/TOP100.htm. In particular, the distances
|
||
# given are derived from RECONS's weighted average parallaxes, rather than
|
||
# pure Hipparcos data.
|
||
|
||
# Orbits are obtained largely from the Sixth Catalog of Orbits of Visual
|
||
# Binary Stars (http://ad.usno.navy.mil/wds/orb6.html) and the Ninth
|
||
# Catalogue of Spectroscopic Binary Orbits (http://sb9.astro.ulb.ac.be).
|
||
|
||
# For binary orbits, the direction of an orbit's node on the plane of the
|
||
# sky is often unknown - the orbits given below will appear correct when
|
||
# viewed from Earth, but the true orbit may be tilted either towards
|
||
# or away from the Earth.
|
||
# For a few orbits the nature of the node is known - these are
|
||
# marked with the phrase "fully specified orientation".
|
||
# Barycenters positions are mainly based on mass estimates from RECONS:
|
||
# the figures used are added as comments belows.
