// @DisplayName: Harmonic Notch Filter reference value
// @Description: Reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter
// @Description: A reference value of zero disables dynamic updates on the Harmonic Notch Filter and a positive value enables dynamic updates on the Harmonic Notch Filter. For multicopters, this parameter is the reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter. For helicopters, this parameter is set to 1 to enable the Harmonic Notch Filter using the RPM sensor set to measure rotor speed. The RPM sensor data is converted to Hz automatically for use in the dynamic notch filter. This reference value may also be used to scale the rpm sensor data, if required. For example, rpm sensor data is required to measure motor RPM. Therefore the reference value can be used to scale the RPM sensor to the rotor RPM.
