Remarks

the data in each line are computed from one monthly orbital arc by GEODYN-II program in reference (N, E, U) to ITRF2008 from the best 10 – 18 stations per arc, range bias and time bias are not included

geocentric X, Y, Z coordinates for each station are computed for intersection of telescope axes, corrections to markers you can to find in ftp://cddis.gsfc.nasa.gov/slr/slrocc/ecc_xyz.snx

the lines with the number of points (columns D+E) lower than 50 should be reject, other criteria are also possible eg. 20 points or 3D standard deviation of the position determination (column U)

the station velocity is inclination computed from the data in columns C and X, Y, Z or AA, AB, AC

the data of several stations from September 1983 to May 1985 and November-December 1986 were not computed due to residuals problem, data problem was also in February 2012

The utilization of the data presented here in publications or presentations requires contact with Stanislaw Schillak
