Elliptical Sources

[jenniferyee]

This paper by Heyrovsky & Loeb: https://ui.adsabs.harvard.edu/abs/1997ApJ...490...38H/abstract

was brought to my attention. It provides analytic results for calculating FSPL magnification for an elliptical source. This is another magnification method that could be implemented in the future.

I think Nick Rattenbury published a paper with an estimate of source ellipticity. It's the only paper about that I remember.
