A second slider defines a latitude band
for linearly interpolating around the shared parallel, which can smooth the crease along the parallel where the two projections join.
The biggest disturbance Cassini had previously witnessed on Saturn occurred in a latitude band
in the southern hemisphere called "Storm Alley" because of the prevalence of thunderstorms in this region.
None of the 1,558-or-so clear images of sites in that latitude band
shows a dust devil in action.
