M. data included in standard data file: no 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) -0.330" -0.050" R.M.S. (root mean square) 0.477" 0.257" Format. 1. Year of the moment of observation 2. Month of the moment of observation 3.
