Homestake Meeting Minutes, 03/23/17

Attending: Andrew, Daniel, Pat, Ross, Levi, Vuk, Victor, Voon

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
  • Parameter estimation for Rayleigh and Love (Pat/Levi)
