Why is the probability distribution of noise inconsistent with the covariance of the model？

[wujilingfeng]

In your example, you set the T orientationNoise = 0.025;, but the OrientationMeasurement's covariance is onsistent with $N\left(0,0.05^2\right)$

what do you mean by "0,0.05^2" ? there is a comma and a decimal point there! and where do I find this value exactly in the code? I didn't find it.
