# The astro/py-astropy-iers-data port

## py3-astropy-iers-data-0.2025.9.1.0.42.11 – IERS earth rotation and leap second tables for astropy

## Description

    astropy-iers-data provides access to the tables provided by the
    International Earth Rotation and Reference Systems (IERS) service,
    in particular the Earth Orientation data allowing interpolation of
    published UT1-UTC and polar motion values for given times.

    It is not meant to be used directly, but by the core astropy package.

    The UT1-UTC values are used in Time and Dates (astropy.time) to provide
    UT1 values, and the polar motions are used in astropy.coordinates to
    determine Earth orientation for celestial-to-terrestrial coordinate
    transformations.
