Predicted diffracted irradiance profile at the SIM telescope entrance aperture plane. This is the nominal case heat shield alignment and spacecraft pointing, at the largest solar diameter when the spacecraft is at its minimum perihelion distance of 0.28 AU. The labels above the curve show where the attenuation provided by each baffle (starting with the spacecraft heat shield) occurs. The vertical lines indicate the dimensions of the telescope aperture, A1.
