For each transport parameter set, represented in the K₀/L – L plane, the best p-value distributions of all the 12 channels (five pulsars) are shown in the left (right) panel. The colour coding represents the increasing p-value from darker to lighter colours. The benchmark models MIN, MED, and MAX are represented with a triangle, square, and circle symbol, respectively. In addition, the best transport parameter set is highlighted with a diamond symbol.
