EOP data row.

Added in version 7.3.0.

This is a structured NumPy datatype used to represent a row of EOP data in the eop_data class. The fields in the datatype are:

  • the UTC MJD,

  • the UT1-UTC difference (in seconds),

  • the \(x\) component of the polar motion (in arcsecs),

  • the \(y\) component of the polar motion (in arcsecs),

  • the \(x\) component of the correction to the IAU 2000/2006 precession/nutation model (in milliarcsecs),

  • the \(y\) component of the correction to the IAU 2000/2006 precession/nutation model (in milliarcsecs).
