| + | * tried to run the radiometer on the data around 1.5 Hz, which seems to be coming from a direction about 68 degrees east of north. Find that radiometer gives 22 degrees north of east, which seems consistent. Some concerns: the data at this frequency has periodic turn ons/offs, so it may be local, in which case the waves would not be plane waves. | ||
| + | * Looked at earthquakes too, but not ready to present. | ||
| + | * Plan to present at the next meeting, will try to have some slides with applications to different data. | ||

Up to 1000x better noise in the Homestake array at 2mHz, depending on the frequency. ross_comparison_vertical.png | + | * Circulated a figure comparing power in Homestake and Pinon flat arrays.

| * Will use this for the methods paper, didn't see the very long periods in the Pinon Flats. Will use to demonstrate why Homestake data can reveal these periods. | * Will use this for the methods paper, didn't see the very long periods in the Pinon Flats.
