complete_recon_ev

The routine complete_recon_ev calculates all of the desired physics quantities for the reconstructed event. This is the place to put experiment specific calculations of physics quantities (or directly in results_write, for simple calculations). For each event, the spectrometer quantities must be passed to the routine (through the 'main' structure), and the following quantities are calculated:

-The unit vectors for the outgoing electron and hadron: $\hat{p_e^\prime}$and $\hat{p_p}$.

-The virtual photon quantities: $q, \hat{q}, \omega, Q^2$, and $\epsilon$.

-The angles between the virtual photon and the outgoing hadron (following the pion production conventions - should the $\phi_{pq}$ definition be different for (e,e'p)?): $\theta_{pq}$ and $\phi_{pq}$.

-Missing momentum and it's components (parallel/perpendicular/outofplane for physics, x/y/z for Heepcheck): P_m, P_m^Par, P_m^Per, P_m^Oop, P_m^x, P_m^y, P_m^z.

-Invariant mass: $W = \sqrt{M_A^2 + 2 M_p \omega - Q^2}$.

-FOR (e,e'p) ONLY: Missing energy and recoil momentum:E_m, T_rec. $T_{rec} = \sqrt{ P_m^2 - M_{rec}^2 }$, and $E_m = E_e + M_p - E_{e^\prime} - E_p - T_{rec}$.
