Dear IGS collegues,
Over the last few weeks there has been an unusual
behavior of the station coordinates time series at the
station ZWEN. The people responsible for the station were
notified last Wednesday and are working on resolving the problem.
The station could probably still be used in
the analysis but not for the alignment to ITRF (as it is one
of the RF stations). In the recent weeks combination, it was
exceeding the 5 sigmas/50mm tresholds fairly systematically.
Time series of the residuals for the station can be found in:
ftp macs.geod.nrcan.gc.ca
cd /pub/requests/sinex/ZWEN
get ZWEN_IGS_N.ps
get ZWEN_IGS_E.ps
get ZWEN_IGS_h.ps
Best Regards,
Remi,
