Subject: coherence v. time for 2 accelerometers 

I used the coh_carpet.m function from the mDV to calculate this plot:

coh_carpet('C1:PEM-ACC_MC1_X','C1:PEM-ACC_MC2_X',gps('now - 3 days'),3600*12,4,10,64)

It shows the coherence v. time of two of our X-direction accelerometers starting around 1AM on Friday and going for 12 hours.

I'm not sure what it means exactly, but it looks like the coherence is relatively steady as a function of time. I will need more RAM than Rosalba or a smarter code to calculate longer time stretches.
