Tycho-2 WDS Supplemental stars

Last Updated: January 10th 2017


  • Fixed the miss spelled name of the SDB to Supplemental was Suplemental
  • Compiled using Object type Double Star rather than "Star"
  • Cleaned up the assignment of the fields for cleaner looking data

This file contains stars specific to double stars as found in the Washington Double Star catalog. These stars, 4,778 of them, will help fill in some areas although most likely not "all" areas whereby one of the companion stars is not available. That is cannot be found in the NOMAD catalog, the Hipparcos/Tycho, UCAC4, GSC, etc.
