Astronomy; Precession data co-ordinate systems

1. The problem statement, all variables and given/known data



Use a coordinate conversion application to roughly map out the amount of precession in coordinate

positions (R.A and Declination) in the sky between 1950 and 2000.





2. Relevant equations



I can easily find a converter on the internet



3. The attempt at a solution



I am a little flabbergasted at what this question means. Can anyone explain it to me?



Where would I get this data?



Thanks,
