Basically just implementing the following expressions

$$ m = H(\alpha) + 5 \log_{10} (d_{\rm ast, \odot} \cdot d_{\rm ast, \oplus}) $$

$$ H(\alpha) = H - 2.5 \log_{10} ((1 - G) \phi_1(\alpha) + G \phi_2(\alpha)) $$

$$ \phi_1(\alpha) = \exp(-3.33 \tan^{0.63} (0.5 \alpha)) $$

$$ \phi_2(\alpha) = \exp(1.87 \tan^{1.22} (0.5 \alpha)) $$
