Homestake meeting minutes, 03/05/15

Attending: Victor, Tanner, Noah, Vuk, Daniel

Our agenda:

1) Homestake status (Tanner, Gary, Daniel)

• stations duty cycle: Tanner hasn't seen any interruptions in the data flow. A few weeks ago there was a strange issue: mass positions for 4100D for two days got lumped into one day file. Will have to deal with this scenario in the code that makes frames, working on implementing this. Added data quality from the surface Q330, so that we can check the clock quality there for diagnostic purposes later.
• data flow: Daniel: data coming in, trying to convert antelope files into a different format for analysis. Tanner: data is being forwarded to IRIS, started last week. Victor: there may be something wrong with the instrument response information, will have to follow up on this.
• frames: making frames (mid February now, trying to catch up)
• data quality shifts: working on the data quality monitor, need some time for it.

2) Planning next visit (Mar 23 - Apr 3)

• locations, foam panels, granite tiles, network, GPS: Vuk had a discussion with Bryce et al. They are currently installing the fiber at the 2000 level. Currently planning 3 stations there.
• 2000 level:
• batteries, chargers
• radios

3) Analysis of existing data

• radiometer approach (Noah, Tanner): pdf
