Radiometric calibration factors as a function of the radial distance of the star images from the center of the occulter. The solid red line is the average value of ϵVL. The solid gray line represents the on-ground value of the radiometric calibration factor. The dashed gray and red lines depict the uncertainties of the on-ground and in-flight radiometric factors, respectively. The vertical solid black line is the radius of the internal occulter in pixels.
