Updated Binary Star Catalogue

Post #1by LukeCEL » 14.10.2020, 22:06

Hi everyone,

A while ago on the Motherlode, I uploaded a catalogue of binary or multiple stars in Celestia, replacing 130 or so stars (with Bayer or Flamsteed designations) with binary systems using available data. Unfortunately, at the time of writing the Motherlode is still not functional, so I can't upload the newer version there yet. So I'll upload it here.

The previous version used a haphazard combination of Excel spreadsheets and hand-editing to create the finished file. This has been complete overhauled, and automatically generates the final .stc file from a source catalog (catalog.txt), using a Perl script. Likewise, the source catalog has been updated as well.

Other changes include:
- Updated coordinates and parallaxes w/ Gaia DR2 values from SIMBAD.
- New sources to estimate parameters (e.g. Mamajek's table, Straizys & Kuriliene (1981)).
- Added over 80 systems, and improved many others.
- Removed 15 Sge (brown dwarf), and nu Oct (possible exoplanet host).
- Fixed duplicate del Ind.

Special thanks to SevenSpheres and pedro_jg for correcting errors and suggesting various improvements.

Here's a small update to this file - it adds a few missing TYC and HD designations not present in the earlier file.
