Hα cloud densities Ne as function of distance to the red giant rRG. The dashed line is the power law fit 
to the derived values. The dotted lines illustrate the expected molecular hydrogen density NH2(rRG) in the red giant wind for a wind velocity of v∞ = 10 km s-1 and mass loss rates Ṁ = 10-5 and 10-6M⊙/yr.
