The astro/py-astropy-iers-data port
py3-astropy-iers-data-0.2025.9.22.0.37.25 – 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.WWW: https://docs.astropy.org/en/latest/utils/iers.html
