Dear colleagues,

during the Final combination of the weeks 1241 and 1242
we had a bug in updating the Bulletin A tables.
This caused wrong values for AC LOD BIAS in Table 6 of
the Final summaries, and small errors in the ERP solutions
(LOD up to 0.006 ms, UT up to 0.050 ms).
All other products were not affected.

We resubmitted all the products to CDDIS.
Sorry for the inconveniences.


Additionally, we fixed a longer existing bug in the alignment
of the orbits to IGS00.
The orbits for the whole week are rotated using
the SINEX transformation results from Remi Ferland.
Then a finetuning using the daily ERP-fluctuations at each AC
is performed. The second step was not corrected for the already
performed "weekly" rotation. Starting week 1241 this bug
was fixed.


Best regards

Gerd Gendt
