Motion sensor graphs include 10-axis motion sensors for Insight and EPOC+ headsets:
Quaternion 0, 1, 2, 3 - quaternion data in X, Y and Z directions and absolute quaternion values
AccX, AccY and AccZ - accelerometer in X, Y and Z directions
MagX, MagY and MagZ - magnetometer in X, Y and Z directions
Motion sensor graphs for older Insight and Epoc+ headsets (firmware < 0x633) include 9-axis motion data:
GyroX, GyroY and GyroZ - gyroscope in X, Y and Z directions
AccX, AccY and AccZ - accelerometer in X, Y and Z directions
MagX, MagY and MagZ - magnetometer in X, Y and Z directions
