Fig. 5

Plot of a monochromatic “orientation map” on the hyperbolic plane. We used the spectral parameter \(\omega= 18\) in units of the disk’s radius. Because of the growth factor in the modulus of the \(e_{\omega, b}\), drawing a picture in which discretization effects do not appear calls for using more propagation directions than it did in the Euclidean case: 200 directions were used to generate the drawn picture
