 | `gain`                  | Determines the influence of the gyroscope relative to other sensors.  A value of zero will disable initialisation and the acceleration and magnetic rejection features.  A value of 0.5 is appropriate for most applications.                                 |
 | `gyroscopeRange`        | Gyroscope range (in degrees per second).  Angular rate recovery will activate if the gyroscope measurement exceeds 98% of this value.  A value of zero will disable this feature.  The value should be set to the range specified in the gyroscope datasheet. |
 | `accelerationRejection` | Threshold (in degrees) used by the acceleration rejection feature.  A value of zero will disable this feature.  A value of 10 degrees is appropriate for most applications.                                                                                   |
