I would like to calculate with high-accuracy the apparent geocentric positions of this three: Spica, the sun and moon. I will apply the following corrections for Spica:
1. proper motion
2. precession
3. rotation of ecliptic
4. stellar aberration
5. annual parallax
6. gravitational deflection
7. nutation
My questions:
1. Is there any particular order in which these corrections must be done?
2. Do I correct for gravitational deflection for sun and moon too?
3. Do I correct for light-time movement and aberration for moon?
Thank you.
