Calculation of "xxx_cov / xxx_std" in v1.1.0 [1.1.0] - 2025-01-24

Hi, In v1.1.0 [1.1.0] - 2025-01-24, there is a change in 'renamed uncertanties component from xxx_cov to xxx_std'. Does that mean the calculated in 'xxx_std' is the standard deviation, not the covariance? Or do we need to calculate the standard deviation from this variable (and how)?

As per the referred article, the covariance associated with eigenfrequencies and damping ratios was calculated.

Dear @SwarupMahato, sorry for the late reply.
The output of the uncertainty calculations is the standard deviation of the relevant property (natural frequency, damping, modal displacement of the dof).
