Schematic of our model. The cyan shaded area indicates the star-forming disk and the large blue stars represent the OB stars within it. The gray shaded areas indicate the eDIG cloud layers, and the filled cyan circles show the eDIG clouds within them. The small purple stars represent the HOLMES between the cloud layers. The colored arrows indicate the source radiation fields of leaking midplane H II regions (S​_OB(λ); blue), HOLMES (S​_HOLMES(λ); magenta), and transmitted radiation (S​_t(λ); cyan). Black arrows indicate the cloud diameter (d) and the layer separation (s).
