BEA interrim report

On page 47 it is quoted:

The company that operates the satellite used by AF447 has provided the traces of the messages transmitted to the aircraft and seen by the satellite.

Why isnīt the log attached ? Why didnīt BEA take this into their calculation ?
The NOC-log (telemetry-transponder data) from Inmarsat would also include crucial data type strength of transmission signal an timing of packages etc.

As the infamous gap of 31 seconds EXISTS in the report, it should ALSO included the telemetry of all these ACARS. If, for example the signalstrength is fixed all the way with a small variable, we could directly calculate that the a/c kept is fligth level in bad weather, but if signal was degrading all the time we could calculate from what timing the degradation occurs and pinpoint approx at what ACARS-message that the a/c starts to divert.

My impression is that BEA has a copy of the telemetry-read out for this date from Inmarsat Noc, otherwise they should ask for a copy a.s.a.p.
