AstroStandard time constants.
Overview
The AstroStandards rely on reformatted time constants files. Dr. Dane Bass shared his converter script that takes the finals2000 files and turns them into AstroStandard compliant formats. Every day, at 6AM mountain time, AsterismAI pulls them, reformats them, and posts them.
Full time constants
The full time constants file dates back to 1973.
As a result, it can have a lot of entries.
Reduced time constants
This is the exact same output as above, only tail-ed to the last 1200 entries. Good for any dates in the last ~3 years.
