The three benchmark algorithms for predicting the location of dark matter halos are, for the most part, all over the map. Most of the test skies look something like this:
There are, however, some skies with rather strong halo signals that get a decent amount of agreement:
The Lenstool MLE algorithm is the current state of the art. As such, it’s the algo to beat. As of this morning, there was only one entry on the leader board with a score topping this benchmark.
*cracks fingers* – Let’s see if we can give it a run for it’s money.
Using “average distance from lenstool ” as the metric, I found that Grided Signal and MLE got significantly worse going from 1 to 2 to 3 DMHs.
I can believe that. My approach is able to nail the first DMH, but stuggles to locate 2 and 3.
