Abstract
We modelled the distribution and the kinematics of HI in the inner Milky
Way (R <R⊙) at latitude b = 0∘
assuming axi-symmetry. We fitted the line profiles of the LAB 21-cm
survey using an iterative approach based on the tangent-point method.
The resulting model reproduces the H I data remarkably well, with
significant differences arising only for R ≲ 2 kpc. This suggests
that, despite the presence of a barred potential, the neutral gas in the
inner Milky Way is distributed in a fairly axi-symmetric disc.
