All Figures

Figure 1: Data (diamonds), the modeled fits (solid lines), residuals (crosses) are shown for the transit of HD 209458. Typical error bars are shown in the upper right hand corner of each plot. The model transits were determined by using the best fit of 362 models to the HST data. Note that there is still a small amount of symmetric residual in the HST fit, which has been increased by a factor of 10 for clarity. Note also the strongly asymetric residual in the b passband, the cause of which is unknown.

	Figure 2: This figure shows the b-HST and v-HST color change during the transit, along with the signatures from LTE PHOENIX models. Note that the systematic noise evident in b is also evident in the b-HST color change. The observed v-HST color change is very consistent in shape, if not in amplitude, to the model.

	Figure 3: This figure shows the v-HST color change for a star with solar metallicity,  K, and , with planetary parameters and . The solid line shows a model assuming LTE while the dashed line is a fully non-LTE model. Note that the latter demonstrates a stronger signature, yet still predicts a significantly weaker signature than the one observed.
