The tables contain the parameters of the development as functions of time t (expressed in centuries since J2000.0) for the non-polynomial part of the Celestial Pole Coordinates X and Y and the Celestial Ephemeris Origin, in microarcseconds.
X=-16616.99 + 2004191742.88t - 427219.05t2 - 198620.54t3 -46.05t4 + 5.98t5 +Sumi)j=0,4 [a{s,j})i*tj*sin(ARG) + a{c,j})i_*cos(ARG)]*tj]
