Pulkovo NEO Page . ... EPOS Software Package . ... EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

Next: Standard stars Up: Extinction and transformation Previous: Equations of condition . ... It is better to have 5 observations each of 30 standard/extinction stars, than to have 3 observations each of 50 stars; in the latter case, we are spreading the same observational weight over nearly twice as many parameters. ... In sum, though one can hardly have too many observations of standard stars, one should not go beyond the optimum number of stars recommended by the planning program. ...
