Predicted intensity of scattered light. The cloud model is J13 with W = 1. Frames a–f: bands R, J, H, K_S, 3.4, and 4.6 μm, respectively. Only the scattering of the external radiation field is included and the effects of attenuated sky background are not included. Frame e indicates areas used for correlation analysis, the larger area drawn with thin line (excluding the sources B1-B3) and the smaller area with thick line (see also Fig. 8).
