Clears (zeroes) the Mode Indicator in the lower left graphics area.
If the band cursor is displayed, the Indicator is cleared in the cursor band.
The Mode Indicator is used by the Polynomial methods on the Frequency & Damping tab for curve fitting FRF data at each counted resonance.
Smooths the Mode Indicator to remove noise peaks. An exponential window is applied to the Mode Indicator to smooth it. (See Transform | Window Data | Exponential command for details).
Each time this command is executed, more noise peaks are removed but the resonance peaks will become wider, meaning that the modes become more closely coupled.
