Notes. Linear or quadratic relations for K(Λ, z) = a + b ⋅ z[+c ⋅ z2] mag applicable to TRGB stars for z < 0.03 for linear relations and for 0.005 < z < 0.03 for quadratic ones. Quadratic relations were adopted if nonlinear behavior is discernible from inspecting the computed values of K, which assume no host reddening (E(B − V)host = 0.0 mag).
