Comments.
All these observations as relative to Titan
are in the portion sm0028
evaluation: The differences O-C(alpha)e, O-C(delta)e were
calculated by N.Emelianov with the theory by
Harper & Taylor. One positions with gross
errors were excluded.
With these O-C one have
alpha delta
M. (mean) 0.600" -0.476"
R.M.S. (root mean square) 0.719" 0.580"
Format.
1. Year of the moment of observation
2. Month of the moment of observation
3. Day of the moment of observation with decimals
4. Number of satellite (N sat)
5. Hour of right ascension (alpha, h)
6. Minute of right ascension (alpha, m)
7. Second of right ascension (alpha, s)
8. Degree of declination (delta, deg)
