(Top) simple RDI subtraction of the F444W images of Vega and Deneb to search for disk emission. Arc-shaped annuli laying between the major Vega diffraction spikes were examined for disk emission as a function of distance from Vega. The dotted box denotes a region used as a background region to measure emission away from the annuli. (Bottom) the blue and orange lines denote emission within the partial annuli as a function of separation from Vega minus the background level in a vertical band at the right side of the image. The feature at ∼10″ is an artifact visible in the image and in the background trace and is due to the edge of the coronagraphic optical mount.
