<short_desc>Cutoff frequency for angular acceleration (D-Term filter)</short_desc>
<long_desc>The cutoff frequency for the 2nd order butterworth filter used on the time derivative of the measured angular velocity, also known as the D-term filter in the rate controller. The D-term uses the derivative of the rate and thus is the most susceptible to noise. Therefore, using a D-term filter allows to decrease the driver-level filtering, which leads to reduced control latency and permits to increase the P gains. A value of 0 disables the filter.</long_desc>
