Schematic of the constant-aspect-ratio disk geometries with a lamppost corona emitting constant emissivity over a boundary (circle in each panel). The green disk has ﹩\frac{h}{\rho }=1﹩, the blue disk has ﹩\frac{h}{\rho }=0.5﹩, and the orange disk has ﹩\frac{h}{\rho }=0.1﹩. In the leftmost panel, with h_c = 5 r_g, the region of constant emissivity makes first contact with the inner radii of each constant-aspect-ratio disk. In the second panel from the left, h_c = 10 r_g, we see that this region of constant emissivity intersects the disk at larger radii for ﹩\frac{h}{\rho }=0.1﹩. In the third panel from the left, an equivalent region of constant emissivity still reaches the inner radii of the disks with ﹩\frac{h}{\rho }=0.1﹩ and ﹩\frac{h}{\rho }=0.5﹩. In the rightmost panel, at h_c = 20 r_g, this region instead intersects the disks with ﹩\frac{h}{\rho }=0.5﹩ at larger radii. The lack of illumination of the inner accretion disk in each case leads to a corresponding decrease in the number of the most highly redshifted photons in the resulting line profiles.
