  1. Overview of the iterative DOE approach leading to, in this case, one sensitivity control parameter Smht. Frozen refers to fixed value after conclusions were drawn using the responses of the active set. The parameters P x 0 , P y 0 , P z 0 , S ω 0 are the diagonal elements of the initial covariance matrix in the tracker.
