Throughput as a function of radial position for a D/50 pinhole for three different coronagraphs. Both the vortex coronagraph and the four quadrant phase mask coronagraph have higher throughput than a Lyot coronagraph with a 2 λ/D circular opaque mask, which shows that the phase mask coronagraphs with small inner working angles are preferred. Both the SM-SCC and the classic SCC limits are shown. The SM-SCC throughput is almost two orders of magnitude larger than the SCC limit.
