Difference in StJetMaker2012 vs. StJetMaker2015
- Response to Carl and Zilong's comments in jet meeting at Jan. 8:
source of minor differences in barrel eta/phu distribution
- A couple of quick QA performed:
a. Restrict jet reconstruction eta from [-1, 5] -> [-1, 1]
b. a. + comments out the part "No TPC vertex found"
(* major change in StJetMaker2015: uses all possible vertex if no TPC vertex is found)
- Results:eta/phi distribution, StJetMaker2012 (left, black or red) vs. StJetMaker2015 (right, blue or magenta)
* I draw distributions from tree directly - official library was not necessary
- Conclusion: minor discrepancy originated from newly updated part (case for no TPC vertex found).
Two libraries show exact match for item b.
