    keyword=T1 & T2 triggers in RHRS

    T1 trigger from PVDIS seems narrow, about 25ns, while the original T1 is about 90ns wide. Now I use the original T1 and adjust Redelay2 module so that T1 is consistent with T2, about 10 ns difference. Scalar inputs of T1 and T2 are changed from NIM to ECL, which gives good signals now. I also checked the Retiming signal delay. It is about 720ns between the orginal signal and that one sent to RT module. I will take a cosmic run to check L1A signal later.
