This blog entry is used for recording the ralationship between trheshlod value and ADC of JetPatch trigger. Thanks for Kevin and Stephen's help.
The record is avaliable for run12_PP200. The relationship should the same for near years but I can't make it sure.

The equation is:
E_T = 0.236 * (ADC - 5)

So

JP0(ADC =20 ): E_T ~ 3.5 GeV
JP1(ADC =28 ): E_T ~ 5.5 GeV
JP2(ADC =36 ): E_T ~ 7.3 GeV
AJP(ADC =20?): E_T ~ 3.5 GeV
