1
Progress on the Compton Analysis R. S. Holmes, A. Rakhman

2
Compton X-Sect and Asymmetry

3
The DL response function Di-Gaussian. Parameters are extrapolated with polynomials Extrapolated Other fits: 1. 2D polynomial 2. Variable width Gaussian

4
Observed Compton Spectrum Integrate response Function folded With theory

5
New Systematic Appeared when a bug was fixed Effect is down (at low end) by 2 with new function

7
Accidental Background on the Tail Hint of accidentals Linear Log Add 10 runs (with same gain)

8
Accidentals Easy to See on Low Energy Strip Monte Carlo Data Pulse shape?

9
Monte Carlo of Accidental

10
Pseudo-Effect of Accidentals Data Monte Carlo

11
Sensitivity to Thresholds This must be understood. We have ideas.

12
New Fit Parameters vs PMT Gain Gaussian with Variable width

13
Cuts Parameters versus Polarization of run

14
Polarization vs Run Χ 2 is getting better. It looks like we are ultimately statistics limited

15
Jobs Make sure that ~E and that width behaves reasonable with E. Rewrite code so that it can analyze Monte Carlo Model slow PbWO 4 response. Fix various bugs.
