@ericagol What is compensated summation?
I haven't run them yet, but will get them started today. I should be able to have them up on MAST within 2 weeks. I'll let you know once they...
Hi @sakhawat18 the problem is in installing the `pysyzygy` package, which I coded up years ago before I knew what I was doing! Looks like the install script fails on...
This is a great idea -- will do!
While I'm at it, I should find a better solver for the quartic, as the current one spends a lot of time finding imaginary roots.
I replaced the numerical stuff with analytic expressions when the ellipses are circles, but it only sped up the code by a factor of 10. Currently there's a ton of...
Optimized several things about the code. It's now a factor of < 10 slower than batman for transit calculations, so I'm going to put that on the back burner for...
Switched from the Numerical Recipes algorithm to the open source GSL code for computing polynomial roots so that we don't infringe the (very silly) copyright.
I [implemented an algorithm](https://github.com/rodluger/planetplanet/blob/47b30ea9b7d061645f73c0d111a03de16aef773c/scripts/intersection.py#L72) that finds the roots numerically using Brent's method. This is advantageous in that it doesn't waste time finding imaginary roots and is more stable than the...
Perhaps an even simpler approach: I can relax the assumption of a circular hotspot and allow the user to specify the aspect ratio of an elliptic hotspot. I'd have to...
