EPOCH TIMES DEUTSCH FOR DUMMIES

Therefore a certain coordinate system (equinox and equator/ecliptic of a selected day, for instance J2000.0) can be applied without end, but a list of osculating things for a selected epoch may possibly only be (approximately) valid for the alternatively minimal time, because osculating factors like Those people exampled previously mentioned usuall

If some time difference is smaller, then rather easy and modest corrections to the precession could suffice. If time distinction will get significant, then fuller and a lot more exact corrections have to be used. For this reason, a star place study from a star atlas or catalog based on a sufficiently old equinox and equator cannot be utilised witho
