During yesterday's investigation, we injected a far-field magnetic sweep with the aim of cross-checking and identifying each resonance frequency of the crossbars.

Here is what came out:

It is interesting to see that after the “disconnection” of the WEB motor crate (and disappearance of the noise) there remains something in Hrec that seems to be associated with CEB (47.52 Hz and 47.74 Hz) and WEB (48.09 Hz). This is an indication that we might gain something more in terms of Mpc if we could find and reduce some other sources.
