## Calo weights: RunII vs RunI

- RunII weights:
- Current weights: e.g. p11.13.00/calreco/rcp/
-          p10_CalWeights_plate.rcp
- Optimization of d0gstar simulation
- 50 GeV electrons
- 20 GeV pions
- uniform eta coverage
- no preshower info
- “Special” weights: p11.13.00/calreco/rcp/
-          pmc02_CalWeights_plate.rcp
- As above, using 50 GeV pions and preshower energies in optimization
- DØ notes by K.L.Chan et al also linked from CTF web page

- RunI weights:
- d0cha:/d0library/production/
-                 full_d0reco/csf.rcp
- A variety of determinations
- Mostly optimization of Test Beam data at a few specific eta values
- 10-150 GeV electrons for EM
- 7.5-150 GeV pions for HAD
- 100 GeV pions for ICR
- Normalized so that the weight for ECEM3 =1.0
- Absolute energy scale:
- ACDtoGeV*layer weight
- RunI: 3.71 10-3 * 1.0
- RunII:
-        2.22 10-4 * 16.98 = 3.77 10-3
- No electronic factors used

## Comments:

- Differences between current Run II and  the Run I weights for EM layers are due to the additional “dead material” in front of the Run II calorimeter. When preshowers are included in the weight optimization to compensate for this, Run II EM weights (pmc02) are similar to Run I EM weights.
- Differences in CCMG weights are likely due to using lower energy pions (20 GeV) for Run II weight optimization than done in Run I.         The pmc02 Run II set, obtained using 50 GeV pions is quite similar to   Run I weights in CCMG.
- Differences in CCMG5 and ICD1 are anti-correlated. Run II set seems to be more uniform across both  CCMG and ICD.
- Overall, a reasonable agreement between Run II and Run I weights and energy normalization scale.
