Ferland Dear IGS Colleagues, Please note that the station KOKB has experienced some problems in the last 2 weekly SINEX combinations. Its residuals are on average (27mm, 24mm, 11mm) (N, E, H) with respect to its reference frame coordinates. Since it was rejected from the combination, it did not affect the alignment, That discontinuity also coincide with equipment change at the station as was pointed out to me earlier by Jim Ray. http://igscb.jpl.nasa.gov/mail/igsmail/2002/msg00454.html Since KOKB also is part of the set of 54 Reference Frame (RF) stations, It should not be used any more for reference frame alignment. A procedure similar to the one outlined earlier this week for FAIR will also be applied in this case. Best Regards, Remi,
