Throughput (ηp) for the SCAR designs shown Figs. 7 and 8. The shown throughput is the total throughput of the coronagraphic system. It includes the Strehl reduction of the phase plate, the spatial filtering of the microlenses and the mode filtering of the single-mode fibers. This throughput is achieved through a single single-mode fiber when the planet is located directly on top of an off-axis lenslet. The throughput at other positions varies generally according to Fig. 4, but varies slightly depending on the specific SCAR design.
