Image Details
Caption: Figure 6.
Residual rms as a function of aperture radius. For each aperture radius, a model image was constructed from the recovered light curve and subtracted from the observed image. The dashed vertical line marks the aperture radius with the minimum residual rms. The rms of the sky background in the original image is 17.066 counts.
