“…Instead of creating a 3D PDF (β 14 , R 3 , cos θ ) for intervals in T eff in the undistorted spectrum, we created 4D PDFs (T eff , β 14 , R 3 , cos θ ) for separate E ν intervals in the undistorted spectrum. There were 9 CC and 9 ES PDFs in each of the 4 day/night phases, with E ν boundaries at 4,6,7,8,9,10,11,12,13, and 15 MeV.…”
