Welcome to the gaiaunlimited documentation!

gaiaunlimited is a Python package for querying and constructing selection functions for the Gaia survey. It is developed by the GaiaUnlimited collaboration.

The GaiaUnlimited project is funded by the European Union’s Horizon 2020 research and innovation program under grant agreement No 101004110.

Attention

This package is being actively developed in a public repository on GitHub, and we need your input! If you have any trouble with this code, find a typo, or have requests for new content (tutorials or features), please open an issue on GitHub.

Features

• Query Gaia scanning laws for when a given sky position is scanned.

• Query Gaia survey selection functions for the probabilities that sources of given properties are included in the Gaia catalog.

• Query ready-made Gaia DR3 subsample selection functions for the astrometry and RVS sample.
