For each image the centroid of the source was measured, the total flux in the image was measured, and the standard deviation in the x and y direction for each source was measured. Using these measurements the plots below were made.</ins></div></td></tr>

All plots as a function of distance were made with an x axis as a ratio of the distance to limb at the time. An average value of 960 arcsec was added to the ratios for scaling purposes.</ins></div></td></tr>
