Class FitIERS

java.lang.Object
  jat.timeRef.FitIERS

Deprecated.

public class FitIERS
extends java.lang.Object

International Earth Rotation and Reference Service parameters. Parses and calculates the polar motion for the Celestial Ephemeris Pole and the offset UT1-UTC. Uses either a space delimited Earth Orientation Parameters file or the GEONS algorithm for parsing the IERS Bulletin A. (Currently not using GEONS method, to use the GEONS method, change the parameter 'use_GEONS' to true and place the IERS Bulletin A into a file called 'iers.dat' into the jat.timeRef directory.
