Simulated N_H variations plotted together with the data. We illustrate three different smooth wind configurations, for Ṁ/υ_∞ = 0.7 (cyan), 1 (green), and 2 (red)  ×  10^-16   M_⊙/km, keeping all the other parameters fixed. The solid black line shows the total N_H consisting of the unperturbed stellar wind (green line) and the tail-like extended component. The observations during the eclipse have been omitted.
