Notes.
This value assumes a likely prograde misalignment. The slope of the distribution to the left of the maximum likelihood point is so steep that after integrating about 6% of the probabilities (until 4.8 degrees) the distribution ends. Since in all our measurements we quote a 68% confidence level by integrating 34% of the probabilities on each side of the maximum likelihood point, we can consider 4.8 degrees as both the 68% and 99% lower limit.
