oblateness vs prolateness

I realized today (or yesterday now I guess) that as a side project to my project on the evolution of galaxies that might evolve into luminous red galaxies, I can, with very little additional work, produce the necessary output to look at the question of whether the LRGs are oblate or prolate, as suggested by Scott Tremaine (IAS). Tremaine's idea is clever because it does not require accurate deconvolution or modeling of the axis ratio distribution; it uses the fact that the galaxies are transparent and asks about relationships between apparent axis ratio and projected stellar density. I did the necessary work to make sure the data that need to be carried along with the evolution data are indeed carried along.
