- Figure 1 is made using the TF measured in Bobinone 2.0, with respect to projection shown in Fig.6 of that eLog, here also the MC heating was on, and the 50Hz sidebands magnetic noise is projected as well.
- Figure 2 is a projection of the coherence of CB magnetometers with dark fringe. The projected curves are computed taking the square root of the coherence multiplied by the calibrated dark fringe. Coherences with single channels are shown separately. I think it would be not correct to add them in quadrature, since there is an unknown cross coherence term to account for. Instead the maximum of the three projected curve is probably a good extimate.This plot is done integrating over 8 hours of WSR11 data and the 50Hz sidebands noise is spread over a few Hz.
This result is consistent with the result of Figure 1.
Projections seems to predict nicely dark fringe noise at:
- 50Hz
- 50Hz sidebands (MC heater switching control)
- 10.6Hz line (origing to be investigated)
On the other hand, there is no evidence of coherence with MC,WE and NE buildings magnetic noise.
