The future formation flying PROBA-3 ESA mission will fly the giant solar coronagraph ASPIICS. One spacecraft will carry an occulter disc of 1.42m diameter in front of the Sun. It will cast its shadow onto the 5cm aperture of a Lyot-style coronagraph on-board a second spacecraft that will be positioned 150m behind with millimeters accuracy....

Context. High-contrast hybrid coronagraphs, which combine an external occulter and a Lyot-style coronagraph became a reality in recent years, despite the lack of analytic and numerical end-to-end performance studies. The solar coronagraph ASPIICS which will fly on the future ESA Formation Flying mission Proba-3 is a good example of such a...
