Spectra on ITMY have been measured after implementing the damping filters recently designed (see aLog 6949)

The attached file shows measurements with the suspension and ISI damped for each level (M0/R0/L1/L2)

• In blue, with old filters
• In green, with new filters

As described in the previous aLog for the same measurement on ETMY (see aLog  6432) the effect the filters should provide above 10 Hz is not visible.

Looking at p22 of the attached pdf, an interesting resonance with a high Q appears at 7Hz for roll, vertical and transverse dofs. A new spectra will be taken tomorrow, to confirm its existence.

The data, pdfs, and measurement list in plotallquad_spectra.m have been commited to the svn.

Plotquad_spectra.m and plotallquad_spectra.m have been modified to automatically scale the plots, depending on the boundaries of the data.
