Sketch of the cross-section of a multi-stranded AR model, which consists of (a) Ns = 20, (b) Ns = 60, and (c) Ns = 100, homogeneous strands of densities ρs and radii rs. In the figure, the strands are represented by their external surface of radius rs (thick solid lines). The external medium to the strands consists of coronal material with density ρc.
