pyia provides tools for working with Gaia data. It accesses Gaia data columns as Quantity objects, i.e., with units (e.g., data.parallax will have units 'milliarcsecond')â¨, constructs covariance matrices for Gaia data, and generates random samples from the Gaia error distribution per source. pyia can also create SkyCoord objects from Gaia data and execute simple (small) remote queries via the Gaia science archive and automatically fetch the results.
