Eclipse apodization: realization of occulting spots and Lyot masks

A key element in the Eclipse coronagraph is the apodized occulting spot. For exo-planet detection in the presence of a sun-like star, the intensity transmittance at the center of the spot is specified to be less than 1X10***sup-8***.
