  We consider the one-dimensional equilibrium problem of a shear-flow boundary
layer within an "extended Hall-MHD" (eHMHD) model of plasma that retains
first-order finite Larmor radius (FLR) corrections to the ion dynamics. We
provide a generalized version of the analytic expressions for the equilibrium
configuration given in Cerri et al. (2013) [Cerri et al., Phys. Plasmas 20,
112112 (2013)], highlighting their intrinsic asymmetry due to the relative
orientation of the magnetic field $\mathbf{b}=\mathbf{B}/|\mathbf{B}|$ and the
fluid vorticity $\mathbf{\omega}=\mathbf{\nabla}\times\mathbf{u}$
("$\mathbf{\omega b}$ asymmetry"). Finally, we show that FLR effects can modify
the Chapman--Ferraro current layer at the flank magnetopause in a way that is
consistent with the observed structure reported by Haaland et al. (2014)
[Haaland et al., J. Geophys. Res. Space Phys. 119, 9019-9037 (2014)]. In
particular, we are able to qualitatively reproduce the following key features:
(i) the dusk-dawn asymmetry of the current layer, (ii) a double-peak feature in
the current profiles, and (iii) adjacent current sheets having thicknesses of
several ion Larmor radii and with different current directions.
