| 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.

| 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: most of the Wiener filter work is finished, some polishing remains.
