Hi Tsuneo,

I am sorry I didn't reply earlier. I forgot it. I put a table below. The
first row is run number, and the second is composed of edge like 2200
and a number from 1 to 4. 1 means pol of target and beam is +z and para,
2 means +z and perp, 3 means -z and para, and 4 means -z and perp.
    map<int,int> listRun={
      {69194,22003},
      {69195,22003},
