-) Homestake wiki ready to use, everyone should check that they have read/write access to it.
+Attending: Michael, Peter B, Vuk, Riccardo, Victor, Tanner, Eric, Gabor, Gary, Pat
 ) Status at Homestake (Vuk, Victor, Tanner)
+Vuk: Not much new, still waiting to hear back from SURF about the cost estimates at 1700 and about the battery use restrictions.
 ) PASSCAL communications (Vuk, Gary)
-) UMN test setup (Tanner) (slides)
+Vuk, Tanner: started to look through the Q330 manuals, there is a lot of information, doesn't seem well organized. Will need more time to understand it, and would probably be useful to speak with tech support about it.
+Gary, Victor: Next week there is the geo union meeting in SF, Quanterra and PASSCAL people will be there. Could speak with them
+Vuk to provide some info and questions.
+) UMN test setup (Tanner) ([[https://zzz.physics.umn.edu/_media/groups/homestake/meetings/2013_12_05_homestake_umn_test_setup.pdf|slides]])
+Tanner finished the test setup (see slides), of the style we had at Homestake. Took data for a day. Looks reasonable, although the gain factor might be wrong. Tanner will follow up.
+Gary: non-zero DC is normal. Safe to assume that everything below a few mHz is just garbage and can be ignored.
+Vuk: will write to Passcal to request a Q330, along with the GPS receiver.
+) Analysis of existing data
+a) Wiener filtering (Michael, Jan)
+Michael: most of the Wiener filter work is finished, some polishing remains. New direction is the Hilbert transform: HT of the vertical channel used to get tilt-free estimates of the horizontal channels. Made a causal version of the Hilbert filter, starting to look at applying this to existing data and build a Wiener filter. Also talking to MIT people to apply this to one of their test setups.
+Michael: will prepare a short presentation about this for one of the future meetings.
+Michael: looking for feedback on the paper, hopes to push it forward quickly.
+b) Estimation algorithms (Shivaraj, Eric)
+Eric: started to look at this, started with Shivaraj's code. Trying to get familiar with it, run
+and study it. Begin making some mods etc. Hopefully will have more next time.
+Vuk: should speak with Shivaraj to organize this effort.
+) Next meeting: Jan 9
