Schematic illustration of the forward model Ax = VHΓQx of REXPACO. First, the object x is rotated by the parallactic angles by operator Q. Then, each resulting temporal frame is attenuated by the (time independent) transmission of the coronagraph with Γ, and convolved by the off-axis PSF by application of H. Finally, the field of view seen by the sensor is extracted by V to obtain the object contribution Ax. The recorded ADI sequence is modeled by the sum of Ax and of the nuisance component f, as described by Eq. (1).
