Dimensionless luminosity xl_x, PA, and PD as functions of the dimensionless photon energy, x=E/f_ck_BT_eff. For all the cases presented, β = 0.35. Results for the whole sphere (column a) and upper hemisphere (column b), observed at inclinations of 5°, 30°, 60°, and 90° are shown with blue, orange, green, and red lines, respectively. Results for 1°-wide rings observed at an inclination 90° are shown in column (c) with blue, orange, green, and red lines for ring colatitude of 5°, 30°, 60°, and 90°, respectively.
