Context

  • I've run the second rejection-sampled grid since we've switched to the masked outer kinematics. We discussed the exact points over email and on the previous bullet point.
  • Things are still coming along nice, and I think we might be closing in on the true minimum (assuming we don't think that the current Ts/shapes/angles are anything strange).
  • Takeaways from this new grid:
    • The mass parameters all seem rather well behaved with clear chi2 minima.
    • The shapes are a shakier than the mass parameters but I still think they look nice. The minimum in T is something like ~0.9, with Tmaj having a minimum near ~0.03 and Tmin seems to really prefer Tmin = 0.

Diagnostics

  • First, here are some 1d panels:
Grid D Alone Grid CD All Scales Grid CD Best Scales
For reference, here's the Grid D scaled models plotted in angle space rather than Ts

  • And some statistics for the two grids we have which build this full set of models:

Dynesty

  • I've processed the combined Grid C + D best scaled models with GPR + dynesty. At this stage, we're getting quite consistent results between these cases. I've included a "production" style plot for one of the cases below for reference:
Cutoff nu=0.5 nu=1.5
K=40
K=60
K=80
K=100
K=150

Rejection Sampled Points

  • I ran our rejection sampling routine on the "best scaled" version of our models for reference. Here's what the resulting distribution looks like:
