    Google search and google image search, "IRAF data reduction remove pupil ghost rmpupil command",

    See in "New Mosaic Reduction Capabilities", section, "Removing pupil patterns: RMPUPIL"

    The above is old, hope this helps? What is a pupil ghost?

    Thanks. A pupil ghost is a fixed feature that comes from multiple reflections of the diffuse background from the sky or the telescope pupil. It is seen in flat images when doing photometry
