... If $3.4 kpc \le R \le 8.5 kpc $, then $$ n_{HI}=0.345\ cdot exp \left[ \frac{-Z^2}{2\ cdot (212 pc)^2} \right] + 0.107\ cdot exp \left[ \frac{-Z^2}{2\ cdot (530 pc)^2} \right] + 0.064\ cdot exp \left[ \frac{-Z}{403 pc} \right] $$ If $ 8.5 \le R \le 16 kpc $, then $$ n_{HI}=n_{\infty}\ cdot exp \left[ \frac{-Z^2}{2\ cdot (530 pc \ cdot R / 8.5 kpc )^2} \right] $$ The density distribution is shown in the figure 1. \ ... As one can suppose, for low velocities we get greater luminosity....
