Spectropolarimetric characteristic of the Inogamov-Sunyaev SL model. The upper panels show the dimensionless luminosity xl_x, and the middle and lower panels show the PD and PA as functions of the dimensionless photon energy x=E/f_ck_BT_*. The fiducial parameter set is θ_peak = 30°, i = 60°, β_r = 0.25, and β_eq = 0.4. Column (a) shows the results for various inclinations. The blue, orange, green, and red lines correspond to i = 5°, 30°, 60°, and 90°, respectively. Column (b) shows the results for various colatitudes of the peak θ_peak. The blue, orange, green, and red lines correspond to θ_peak = 5°, 30°, 60°, and 89°, respectively. Column (c) shows the results for various equatorial velocities. The blue, orange, green, and red lines correspond to β_eq = 0, 0.2, 0.35, and 0.5, respectively. In this case, the edge velocity was fixed at β_r = 0.5β_eq.
