Z_EDR3 as a function of G (horizontal axes) and ν_eff (color bar) for the L21b zero point (left column) and the new zero point in this paper (right column). The black lines correspond to the values of the nine ticks in the color bar. To visualize the β effect, each Z_EDR3 is evaluated atthe ecliptic south pole (top panels), equator (middle panels), and north pole (bottom panels). I note that for G < 12.9 Z_EDR3 has no color dependence in the ν_eff = 1.1−1.24 μm⁻¹ range, as q₃₀ = 0. Breakpoints are marked with vertical dotted lines. Compare with the top panel in Fig. 20 of L21b.
