1. T. Burnett: PSF status 3Feb061 DC2 PSF Status The function: 8 bins in energy (2/decade), 6 in cos(  ) (0.1) Two classes A: GoodEvent3; C: GoodEvent1 && ! GoodEvent3; Apply scaling function of energy to angular deviations to make the 68% values for approximately 1. (The “Atwood function) Objective: to find reasonable parametric representation in E and cos  of  and 

2. T. Burnett: PSF status 3Feb062 Fits to the function 8 bins in energy (2/decade), 8 in cos(  ) (0.1) Two classes so far differ in CTBCORE cut. also (front/back) A: GoodEvent3; C: GoodEvent1 && ! GoodEvent3; Combine the two data sets Apply scaling function of energy to make 68% values approximately 1. Stop fit at 10 (scaled) sigma

3. T. Burnett: PSF status 3Feb063 Class A front: Near normal fits for all energies

4. T. Burnett: PSF status 3Feb064 The parameters: polynomial fits 68%   95%

5. T. Burnett: PSF status 3Feb065 Angular dependence: mild class A front

6. T. Burnett: PSF status 3Feb066 What about those Class B guys? Clearly energy-dependent

7. T. Burnett: PSF status 3Feb067 Check integral distributions: compare A, C front currently a mystery factor of 2!

8. T. Burnett: PSF status 3Feb068 To Do Continue checking Decide on strategy: Table look-up Smooth functions
