Dear user of the ocean loading provider.

Aug 27, 2009: BUG REPORT
An error in the refinement stage OLMPP was detected.
Results are affected at the 10% level in the case of
stations near the coast with increasing error toward
high latitudes. The problem started after a revision
on *July 07, 2009*.  Affected results are recognizable
on behalf of the signature "Computed by OLMPP" or
"Computed by OLCMC/OLMPP" in the BLQ output.

Thanks to Kristian Breili and Matt King to point out
the problem.

The problem has been solved ar UT 13:45 today, Aug 27,
2009.
