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 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.
