Systematic Errors (Gen4 and Gen5)

Gen5 uncertainty due to Jet energy corrections:

• Preliminary estimation using jcorr1 by Un-ki Oct. 28

(Runl absolute corr. but uncertainty based on the Jet Workshop) Systematic error is reduced by more than a factor of two
• Preliminary estimation due to L1 systematics using jcorr1 by Un-ki Nov. 16

(Runl absolute corr. but with official uncertainty table), uncertainty is reduced by 30-40% if L1 systematic uncertainty at 0.9<|eta|<2.0 is reduced by a factor of 2.
