The astro/py-astropy-iers-data port

py3-astropy-iers-data-0.2025.1.6.0.33.42 – IERS earth rotation and leap second tables for astropy (cvsweb github mirror)

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.
