Subject: Seismic Confusion 

You are plotting the STS channels, not Guralp. These are for the Trillium 240 seismometer.

Also, you cannot tell if the seismometer is working by plotting the MEAN trend. That just gives the average and we need the fluctuations. Better off looking at the spectrum like I did last time.

And....its not good enough to just do the bubble. You have to do the mass centering procedure that you and I did last time with the breakout paddle.
