An example of how this performs: if a star's posture is measured by someone these days, they then use a typical transformation to get the placement expressed with regard to the standard reference body of J2000, and it is frequently then this J2000 posture that is shared with Other folks.So, some stellar positions examine from a star atlas or catalo
