Content | EOP(IERS) C 01 is a series of the Earth Orientation Parameters given in the 1997 IERS system at 0.1 year interval (1846 - 1889) and 0.05 year interval (1890 - now).It is regularly recomputed to take advantage on one hand of the improvement of the various individual contributions and in the other hand of the refinement of the analyses procedures. This series is the basis of the IERS system.The data are stored in two files: eopc01.iau2000.1846-1899 and eopc01.iau2000.1900-'NOW' (this file). |
