accelerometerInitialBiasZAsMeasurement

Gets accelerometer Z-coordinate of bias used as an initial guess. This value is determined once the calibrator starts. If accelerometerSensorType is AccelerometerSensorType.ACCELEROMETER_UNCALIBRATED, this will be equal to the value used internally by the device as part of the accelerometer hardware calibration. If accelerometerSensorType is AccelerometerSensorType.ACCELEROMETER, then accelerometer sensor measurements are assumed to be already bias compensated, and the initial bias is assumed to be zero. If isAccelerometerGroundTruthInitialBias is true, this is assumed to be the true bias, and estimatedAccelerometerBiasZ will be equal to this value, otherwise estimatedAccelerometerBiasZ will be the estimated bias after solving calibration, which will differ from accelerometerInitialBiasZ.
