Hi, this is not quite the same as what I see. when I ran teh old wc_res.C
on
/net/data/9/Analysis/data/flr-12144.root
... ...
/net/data/9/Analysis/data/flr-13266.root
I got theta_p - theta_p(theta_e) = -0.34deg (eleft), -0.45(eright)
both are almost twice as much as the values from
/net/data/9/Analysis/data/online_crunch/flr-12144.root
... ...
/net/data/9/Analysis/data/online_crunch/flr-13266.root
It s admittedly an old macro but I see similar changes in ed elastic
comparing online against the recrunch. Michael has the detail in a message
I sent to him the day before. I ran the code again today to verify those
figures. were the paths I used correct?
