magnetometer
Size of preliminary subsets picked while finding a robust magnetometer calibration solution. By default this is the minimumRequiredMagnetometerMeasurements, which results in the smallest number of iterations to complete robust algorithms. Larger values can be used to ensure that error in each preliminary solution is minimized among more measurements (thus, softening the effect of outliers), but this comes at the expense of larger number of iterations. This properly is only taken into account if a not-null magnetometerRobustMethod is specified.
Throws
if provided value is less than minimumRequiredMagnetometerMeasurements at the moment the setter is called.
if calibrator is currently running.
