Analysis of the WFPC2 saturated star images indicate that the large angle scattering (>3" from a star) is significantly higher than expected. ... The first set was from the SMOV Ghost Check proposal 5615, in which 100-second images of Cas (V=2.7) were obtained at the center of each chip in F502N. The second set was a series of 6-second exposures of Vega (V=0.0) centered on WF2 through F410M (WFPC2 GTO proposal 5205). ... The source of the WFPC2 scattering may be the CCDs. ...

... In this section, we develop a physical model of the secondary as a disk that is centrifugally supported in the radial direction and hydrostatically supported in the vertical direction. We assume that the disk is vertically isothermal and well mixed. ... where is the mean molecular mass of the gas, is the orbital period at the outer edge of the disk in years, and all of the mass of the secondary has been assumed to be concentrated near its center, so the Keplerian approximation is valid. ...
