The emergent emission spectrum from the (left) north and (right) south hemispheres of the simulation. The solid lines show the total emission, while the vertical dashed line denotes 13.6 eV, where the H I Lyman edge is expected to occur. The spectra are computed for different heights (z) ranging from ±100r_g to ±250r_g, with the x boundary extending from 50r_g to 220r_g. Note that by z  ≳  200r_g, the top/bottom boundaries do not intersect any photosphere within the x range we consider.
