Final probability distributions of the signal of β Pic b from the 2019-11-26 data set of β Pic, using an aperture radius of 1.85 pixels. Left: probability distribution of the total intensity. The mean and 68.27% uncertainties of the distribution are shown above the graph, with the latter also indicated by the light-blue shaded area. The S/N is shown within parentheses. Right: probability distribution of the degree of linear polarization. The upper limits computed from the one-sided 68.27 and 99.73% intervals are indicated by the light-red and darker red shaded areas, respectively.
