Dataset for Narrowing the parameter space of collapse models with ultracold layered force sensors

<p>PSD - Original power spectral densities at different temperatures (in mK). For accounting the spectral leakage due to the&nbsp;FFT resolution, one has to remove the central 6 points. The columns are: frequency (Hz), value of PSD (Phi_0^2/Hz), PSD error (same units)</p> <p>Final data - Excel reporting the results of the PSD fits and that of the linear fit of B for the high&nbsp;temperatures. Final upper bound for the value of S_{F0}</p>
