Summary of the free parameters (first column) and the interval over which a uniform prior was assumed (second column) and their most likely value for each of the three fits performed, to minimise the residuals in polarised intensity with IRDIS (third column), in total intensity with NICMOS (fourth column) or the combination of polarised intensity with IRDIS, and total intensity with NICMOS and IRDIS (fifth column).
