Projected spin-orbit alignment of solar-type binaries. Full vertical lines indicate 68% confidence intervals. The median projected spin-orbit angle is marked with a short horizontal line. The most likely projected spin-orbit angle (using the mode of the posterior) is indicated with a black square. For systems in which Δi_mode falls outside the 68% confidence interval (typically if i_mode = 90°), a dashed line indicates the extension of the confidence interval.
