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.

@abdabdul i think @wujilingfeng is saying that the noise is consistent with a normal distribution with mean mu = 0 and standard deviation sigma = 0.05 (variance sigma^2 = 0.05). But if this was true, the variance would then be 0.0025, hence the issue
