[MPU-6000] Gyro bias compensation?

Hi InvenSense team,

I'm evaluating MPU-6000 (rev D). The below image shows the gyro data in deg/s when the chip is stationary.



As you see, the bias values are quite random.
For the X axis, it seems that I can compensate for the bias by adding +0.0153 to each data sample.
For the Y axis, the offset value is large (-3.9389) and even more random, so I cannot use the above method to compensate for the offset.

Is there any way to solve this problem?

Thank you.
