=================

Package `pygaia.utils`

This package provides pygaia utility functions.

* :py:mod:`pygaia.utils.construct_covariance_matrix` provides a convenience function for constructing covariance matrices from the astrometric and radial velocity uncertainties and correlations listed in the Gaia Catalogues.
* :py:mod:`pygaia.utils.gaiadr_timespan` provides the precise time spans of the data collected for each Gaia Data Release. The time spans can be used, for example, when simulating Gaia observation times with the `Gaia Observation Forecast Tool <https://gaia.esac.esa.int/gost/>`_.
