Robin provided 2 more tables so I made a new fit to get the "I VS P" curve. I provided the fitted functions to Javier and also cc email to g2p_ana@jlab.org. I have also mentioned it in the 4:15 meeting.
The new fit is slightly different from the old one. It will be better in the high current region when the iron starts to saturate. I scaled it to the old curve at 1.705 GeV, which is the elastic point of this beam energy. As you can see, it is within 1A difference compared to the old one.
