We reset this today. It appears to be back where it was. Several analysis centers (ACs) are still apparently using the data from NISU instead of those from NIST. Station NIST is our primary station in the IGS. The IGS website lists several ACs using NISU data, yet they are not in the list for NIST. These stations are: NRCan, GFZ, JPL, MIT, and ESOC. Please consider using the data from NIST. Best Regards, Marc Weiss ____________________________________________________________________ Marc A.
