-    - Vuk updated the directional analysis note: {{groups:homestake:analysis:directional_analysis_v2.pdf|pdf}}. The note now includes the calculation for Rayleigh waves, following the discussion between Victor, Eric, and Vuk at Caltech several days ago. Results are similar to P-waves, with the distinction that there is an exponentially decaying factor (with depth) and a different coupling of the wave to the seismometers' channels. +Vuk updated the directional analysis note: {{groups:homestake:analysis:directional_analysis_v2.pdf|pdf}}.

 +Vuk/Victor: plan to have multiple tools that we could use to look at the data. Rayleigh waves will dominate at least the shallower part of the array at Homestake, so it will be useful to apply such a tool to understand what component of the data could be explained with the Rayleigh model.
