Schematic drawings of suggested geometry of NS-LMXB in the soft state. Assuming M_NS = 1.4 M_⊙ and B = 2 × 10⁸ G, (a) R_A = 1.2 × 10⁶ cm, (b) R_A = 1.3 × 10⁶ cm, and (c) R_A = 1.5 × 10⁶ cm corresponding to L = 20 × 10³⁶, 15 × 10³⁶, and 10 × 10³⁶ erg s⁻¹, respectively. The HR representing the solid angle of the Compton cloud changed between (a) and (b), while it stays constant in (b) and (c).
