Earth orientation parameters
Earth orientation parameters (EOP) are a collection of parameters that describe irregularities in the rotation of the Earth. The Earth's rotation is not even. Any motion in/on the Earth causes a slowdown or speedup of the rotation, or a change of rotation axis. Most of them can be ignored, but movements of very large mass, like sea current or tide can produce discernible changes and cause error to very precise astronomical observations.
