Notes. Labels of the model parameters follow the notations given in the text: ϖC is the cloud parallax, qC is the cloud’s mean Stokes parameter q, uC is the cloud's mean Stokes parameter u, Cint, qq and Cint, uu are the diagonal elements of the intrinsic-scatter covariance matrix. In all cases, the flat prior on Cint, qu, the off-diagonal element of the same matrix, is defined by 
, 
such that the semi-positive-definiteness of the covariance matrix is guaranteed (thus, excluding the limits). The parallax values of 0.286, 1.667, 3.334, and 10 correspond to distance values of 3500, 600, 300, and 100 pc, respectively.
