Asymmetry analysis of the (e,e'd)p channel:

01.)

I would like to compare theoretical calculations with measured asymmetry. To achieve this, I have averaged the theoretical asymmetry over the available kinematic (E', theta_e) acceptance. I have decided to do this on event by event basis.

Procedure:

1.) Determine E', theta_e, phi_dq, p_Miss for each event
2.) Find the corresponding kinematic bin and select appropriate theoretical calculations.
3.) Neglect all the data, for which theoretical calculations do not exist.
4.) All calculations are made for the center of each kinematic bin.
5.) Using 2D interpolation calculate asymmetry for given combination of p_Miss and phi_dq.
6.) Fill the 2D histogram with the theoretical calculations.
7.) Determine the average and compare with the data.
