Maximum a posteriori probability (MAP) and posterior mean and standard deviation (SD) estimates of the free parameters in intrinsic GRG length distribution inference.

Notes. The model assumes ξ is constant for z ∈ [0, zmax]. We determined the posterior twice: for zmax = 0.5, using 1473 giants, and for zmax = 0.25, using 811 giants.
