Query: Describing the Uncertainties in VLBI Images   We are investigating a new approach to modelling uncertainties in individual
pixels of Very Long Baseline Interferometry (VLBI) intensity (Stokes I, Q, U)
images. Comparison of distributions of our calculated uncertainties for model
sources with the results of Monte Carlo simulations shows that our method
correctly reproduces the overall level and pattern of uncertainties in
intensity images for model sources that are not too compact. Refinement of the
approach to better reproduce uncertainties in compact sources is being studied.
This new approach should ultimately provide a means to correctly estimate
pixel-based uncertainties in the Stokes parameters I, Q and U, including the
effect of correlations between values in different pixels.
