To simplify a little bit the explanations, the equations and parameters provided in these articles implement the IAU 1976 and  IAU 1980 precession and nutation models, respectively (see the IERS conventions 1996 [Denis and McCarthy., 1996]<ref> [Denis and McCarthy., 1996] Denis, D. and McCarthy., 1996.

The procedure to perform an accurate transformation between the coordinate frames ICRF and ITRF is provided as follows (see Transformation between Celestial and Terrestrial Frames)

Transformations between CRF and TRF frames

To simplify a little bit the explanations, the equations and parameters provided in these articles implement the IAU 1976 and IAU 1980 precession and nutation models, respectively (see the IERS conventions 1996 [Denis and McCarthy., 1996][1]). Nevertheless, the IAU resolution B16, recommended that beginning 1 January 2003, the previous models be replaced by the new IAU 2000 model. Procedures and equations implementing such transformations are described in the IERS conventions 2003 [Denis et al., 2004] [2]. The IERS documents and software routines can be found in ftp://maia.usno.navy.mil/conv2003/chapter5/.
