INFORMATION ON UPDATED EPHEMERIDES OF MINOR PLANETS SERVICE Due to rapid growth of number of the numbered minor planets the EMP data turn out to be substantially incomplete or out of date by the time they are used. ... The package computes positions of minor planets by the formulae of elliptic motion using sets of osculating elements obtained in advance for a number of non-uniformly distributed moments of time. ... In so doing coordinates and masses of perturbing planets are taken from DE 405. ...
