Comments.
evaluation: The differences O-C(alpha)e, O-C(delta)e were
calculated by N.Emelianov with the theory by
Harper & Taylor.
With these O-C one have
alpha delta
M. (mean) -0.375" -0.878"
R.M.S. (root mean square) 0.618" 1.165"
Format.
1. Year 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)
