v1.1.1

• Updated output of VT magnitude in the cross-index file
• Some spectral type parser fixes

Statistics:

• 2472034 stars
• 347653 HD cross-index entries
• 254874 SAO cross-index entries

v1.1.1-alpha.2

• Fix for Gaia/HIP distance selection
• Fix for TYC2 supplement 1 identifiers
• Wider magnitude range in ADQL queries
• Increase weighting of magnitude/position relative to other categories
• More robust handling of narrow integer types

Statistics:

• 2472034 stars
• 347653 HD cross-index entries
• 254874 SAO cross-index entries

v1.1.1-alpha.1

• Updated the scoring function for cross-matches to include parallax information and fix relative weights of different fields. From manual inspection of a sample of the changes from v1.1.0, this appears to give much better results.

Statistics:

• 2571533 stars
• 352912 HD cross index entries
• 256767 SAO cross index entries

v1.1.0

• First release version with Gaia EDR3 data
• Add data for HIP1 stars not in HIP2
• Add data for stars in Tycho-2 supplement 1

Statistics:

• 2571647 stars
• 352913 HD cross index entries
• 256767 SAO cross index entries

v1.1.0-beta.1

• Use tycho2tdsc_merge to provide TYC2-HIP crossmatch
• Temporarily disable auxiliary files generation

v1.1.0-alpha.2

• Update magnitude conversion formulae to EDR3
• Use MCMC method to determine HIP2 distances
• Produce auxiliary files

v1.1.0-alpha.1

• Use Gaia EDR3
• Now uses Rust

v1.0.4

• Prefer XHIP distances where the relative parallax error is smaller than the Gaia value.
• Fix Pylint warnings.
• Refactor common parsing functionality.

v1.0.3.1

• Use Tycho-HD cross index (VizieR IV/25) to provide HD identifications for TYC stars instead of ASCC.
• Preferentially use the HD identifications in the SAO catalogue as the basis for the SAO cross-index.
• Merge missing data when combining HIP and TYC subsets

v1.0.2

Fixes an issue where missing spectral types were being converted to O.
