| + | * Pat: Trying to find ways to test radiometer. Found a feature at about 1.5 Hz, that seems to be eastward Rayleigh (90 degree phase between radial and vertical directions). It is human dependent, 12 hour cycle. | ||
| + | * Not all stations see it, some surface and some deep. So this could be a local source, although it is observed in TPK station. Some stations may also see it in the North component, but it is mostly only on the east channel. North to vertical phase is not as consistent as east to vertical. | ||
| + | * Compared results to direct phase measurements between different stations. Currently not getting good agreement, but need to do more work to make sure the comparison is appropriate. | ||
| + | * Victor: agrees, something is not right with the comparison, the polarization directions seems wrong. | ||
| + | * Pat: will look more into this. | ||
| + | * Vuk: should check with people at Homestake (Jaret) if they are aware of anything with this regularity. | ||
| + | * Victor: Maybe has to do with Sturgis, which is in the correct general direction. | ||
