[irr,x,y] = PupilProp(D,lambda,L,F,ObsRatio,N,...
Atm,RandStart,NumRand)Computes the irradiance distribution after propagation from a uniformly illuminated annular aperture. Allows for propagation through Kolmogorov phase screens of arbitrary strength distributed arbitrarily over the propagation path. Defaults to vacuum propagation if screens not specified. When turbulence is specified, returns the average irradiance over random phase screen realizations.
