Profiles of the Fe i 6301.5 Å line computed for six LOS’s corresponding to the colors (purple, blue, pale-blue, green, yellow, red) indicated in Fig. 6 for every μ (top row). Temperature and velocity distributions along these LOS’s are shown in the middle and the bottom rows. Positive velocities correspond to motions away from the observer. The line profiles are normalized to the quiet-sun continuum at disk center.
