Figure 1: What Dante sees in a typical VisRad halfraum simulation, progressively zoomed in. Emission temperature is shown here. 
The question: DANTE sees a different proportion of hot spots, wall, low-albedo witness plate, and LEH/vacuum than does the witness plate.  How do the radiation temperatures and spectra incident on DANTE and the witness plate compare?  How does beam pointing affect the temperatures? How important is it to model these effects when analyzing hohlraum/halfraum data from OMEGA?
