Numerical integrations have been performed and fitted to observations. Ephemerides of the equatorial heliocentric rectangular coordinates of the minor planets are presented under the form of Poisson series, covering 150 years from 1900. The list is presently limited to planets number: 1, 2, 3, 4, 5, 6, 7, and 324 (Ceres, Pallas,Juno, Vesta, Astrae, Hebe, Iris and Bamberga). CONTENTS : 2 types of files are provided: 1 - Time series for heliocentric equatorial coordinates of minor planets, as well as heliocentric and geocentric equatorial rectangular coordinates of the Earth-Moon barycenter under the same form which are necessary for geocentric positions. 2 - Software: A FORTRAN program useful to read the series and substitute the time. It computes geocentric positions. An example of use is given.
