EPOCH TIMES DEUTSCH - AN OVERVIEW

If time difference is small, then pretty simple and modest corrections to the precession may perhaps suffice. If time variance gets big, then fuller and a lot more precise corrections should be used. Because of this, a star situation read from a star atlas or catalog depending on a adequately aged equinox and equator cannot be utilised without havi

So a selected coordinate method (equinox and equator/ecliptic of a specific day, which include J2000.0) might be used permanently, but a set of osculating elements for a particular epoch may perhaps only be (close to) legitimate for just a instead restricted time, due to the fact osculating things such as People exampled above tend not to exhibit t
