Re:Strange Noise in Gravitational-Wave Data Sparks Debate

I mean yeah there's probably lots of instrument telemetry in the data, but let's give LIGO the benefit of the doubt and say that the instrumentation has consistent performance through null control regions of the timeseries and the "interesting" regions of the timeseries (bloop #1, in this case, but apparently now bloops #2, and #3 which were not analyzed by the person doing the criticism).
the 'truckloads' of data are basically all the uninteresting parts of the timeseries. Of course there is statistically going to be random events where the noises correlate at the level seen by the critique, and maybe the truckloads of data show that those are frequent enough that say 1/3 of the bloops should have that correlated noise superimposed on the 'actual signal'; and maybe that bloops 2 and 3 do not have the correlated noise if you apply the same analysis to it.
How much more 'raw data' do you need to reach a conclusions that refutes the criticism?
That kind of gives the lie to the conspiracy that many would like to believe... And before you go demanding that they release the raw data (in addition to the processed data), I hope you are aware of how many disk drives you're going to need to fit into that station wagon.
