Dear colleagues,

The maser at Herstmonceux station had a technical problem on 6th
November. Pierre Exertier from the T2L2 team was able to spot this issue
and kindly let us know. All the 7840 passes from the 6th to the 15th
November previously submitted have a time bias of ~2.8 us (*). We have
re-reduced all the data with the appropriate clock corrections. Users
who fetch the data from the daily CDDIS files should ensure they check
the CRD release flag and overwrite any previous data files.

Although the reason for the fault has not been established yet, the
maser is stable and operations continue as normal. We thank Pierre for
the information.

Kind regards,

Jos Rodrguez
