Normalized azimuthal average for different simulations in the H2 filter (1593 nm) with the SLLC and taking into account various error terms: all sources of errors (red), only phase errors (dark blue), only amplitude errors (green), only the measured transmission map of the SLLC prototype (orange), and finally with only the SLLC nominal design (light blue). The SLLC+FPM data are overplotted as a black dash-dotted line.
