Sketch of the intersection of the sky map pixel i and detector j. The matrix element (i,j) of the projection matrix P is equal to the intersecting area of pixel i with detector j. The sky map pixels are square but the detectors are quadrilaterals because of the distortion of the optics. The distortion is exaggerated in this sketch.
