Pseudo-color map of AL in the galactic coordinate system utilizing the HC method. The blue star and line mark the direction of the largest AL and the corresponding 1σ range in the sky. The direction and 1σ area is parameterized as AL_max,H0 (324.3$°{-34.8}_{+4.76}^{}$, −6.7$°{-39.1}_{+3.0}^{}$). Different from Fig. 3, here only the parameter H₀ is free. The parameters q₀ and j₀ are fixed to −0.55 and 1.0, respectively.
