To return the broad interior transport, the <western boundary current> has opposite sign and characteristic peak
$$
v_W\sim-\frac{F_0L}r,\qquad
\boxed{|v_W|\sim57.3\,\mathrm{m\,s^{-1}},\quad\text{southward}.}
$$
The leading exponential profile retains the smaller interior offset, $v(0)\simeq(F_0/\beta)(1-L/\delta_W)\simeq-52.1\,\mathrm{m\,s^{-1}}$. Because $\gamma L\simeq0.593$ is not very small, the exact two-wall solution gives a more accurate linear-model peak:
$$
\boxed{v(0,0)=A[\lambda C_W-\gamma C_Ee^{-\gamma L}]\simeq-40.5\,\mathrm{m\,s^{-1}}.}
$$
All three evaluations identify an intense southward <western boundary current>, with peak at $x=0,y=0$, of order tens of metres per second. They are predictions of the stated steady linear barotropic model. Nonlinear <advection>, stratification and the actual basin geometry could alter them substantially; the calculation does not establish that real <Pluto> winds attain these values.
