Homestake Meeting Minutes, 03/24/16
Attending: Daniel, Ross, Tanner, Gary, Gwynne, Victor, Levi, Vuk
Agenda:
1) Homestake array
- status of stations (WTP, Yates, 800)
Tanner: UMN antelope went down last Thursday, caught it within a week and copied the data from Homestake. Could not do this for HS, since the data is not available at Homestake. Can get it from baler eventually (one day of data). Gary has access to the HS computer, will try to copy the data directly.
Gary: observe low noise at low frequencies, digitizer may be limiting us. Noel at PASSCAL told us that we could boost the gain from 0 to 32, which will compromise the dynamic range but will lower the noise floor for the digitizer. May be able to do it remotely with Willard.
Vuk/Gary: Suggest to make a change for one of the stations and observe the impact over the next 2 weeks, and decide whether to stick with it or revert back in 2 weeks.
Tanner: will try to do this. Gary will help, contacting Noel.
- planning next visit: April 15-24
2) data analysis updates
UPDATED Results of Geochemical Data Analysis of Homestake
PowerPoint
Updated the calculation, using input from Gary and Victor. The spread in estimated velocities is reduced now, after using the appropriate proxies. Get good agreement with streamer measurements at the 2000 level.
