These allow to compute precession with an accuracy that is comparable to IAU 2006 model close to central epoch J2000.0, a few arcseconds throughout the historical period, and a few tenths of a degree an the ends of the +/- 200 millennia time span. Computer algorithms are also provided. Workplace Astronomical Institute Contact Radka Svašková, bibl@asu.cas.cz, Tel.: 323 620 326 Year of Publishing 2012
