Conditional probability distribution corresponding to the 1D likelihood scan through ϖ_C for the one-cloud mock data set using the one-layer model. The vertical (continuous) green and (dashed) purple segments indicate the true and observed distances of the stars, respectively. The gray oblique lines link the two. The green horizontal errorbars indicate the 68% confidence level on star distances obtained from . The vertical red line indicates the input cloud parallax. Due to randomization on parallaxes, some stars with very similar (true) parallaxes (green) are dispersed.
