gaia-catalog
Bundled Gaia DR3 star catalog in a compact binary format for Python, with Hipparcos 2 data for the brightest stars.
Installation
pip install gaia-catalog
Creating the binary catalog
The binary data file is not included in the repository. To create it from a gaia_merged.csv (produced by tetra3rs's download script):
python -c "from gaia_catalog import convert_csv_to_binary; convert_csv_to_binary('path/to/gaia_merged.csv')"
This writes gaia_merged.bin into the package's data/ directory.
Usage
from gaia_catalog import catalog_path
path = catalog_path()
Binary format
Header: b'GDR3' (4 bytes) + version (u32 LE) + num_stars (u64 LE)
Per star: source_id (i64 LE) + ra (f64 LE) + dec (f64 LE)
+ mag (f32 LE) + pmra (f32 LE) + pmdec (f32 LE)
36 bytes per star, little-endian throughout.
