Appendix A: Scattering Analysis Formulation

Paths of the incident light and light scattered toward the observer for a single particle in an optically thin nebula. The scattering angle thetascat measures the amount by which the light the observer sees has been deflected from its incident path. For mathematical purposes, a parcel of nebulosity is assumed to be small enough that thetascat is essentially the same for every particle; thus the total light scattered by the parcel in a given direction can be represented as a simple summation of N identical scattering events.
