Homestake Meeting Minutes, 03/23/17
Attending: Andrew, Daniel, Pat, Ross, Levi, Vuk, Victor, Voon, Gary
Agenda:
Data analysis topics
Data corrections, frame production (Gary/Daniel/Pat)
Pat observed that some of the channels were swapped (E and N) on some of the stations and not on others.
Daniel: Gary corrected this, will send USB sticks to UMN and Caltech. Pat mailed the sticks to Gary, he should have them by the end of the week. IRIS knows what corrections it needs to apply, but has not done it yet. We should follow up with them in a couple of weeks.
Event catalog (Gary/Ross): no news.
Radiometer updates (Pat)
slides
Total recovered power (in P-experiment) is about 2x too low, and the amplitude in the 90% region is about 20% too low. But position recovered correctly. The issue might have to do with spectral leakage.
When injecting/recovering P+R, there is a bit of leakage from R to P.
Have to think more about assessing the significance of recovered peaks.
Will look at the microseism band, since we can compare with the known directions.
Try recovering with different combinations to gain experience with leakages etc.
Also need to include the bi-exponential Radiometer model.
Parameter estimation for Rayleigh and Love (Pat/Levi)
