Vibration rectification

Hi,

 

A question regarding the vibration rectification parameter:

 

Take the ADXRS453 with a vibration rectification parameter of 0.0002 deg/s/g^2. If this gyro is subjected to a linear acceleration of 100 g for 0.25 seconds, will this give 0.0002 * 100^2 = 2 degrees/second in additional bias? Meaning that during 0.25, this would give 0.5 degrees error in angle...

 

Or am I making a mistake here?

 

I also see that for at least some of the IMU products, this factor is not mentioned in the Data sheet. What is the reason for that?
