// Add Triple coincidence physics module
THaPhysicsModule* TC_n = new THaTripleCoincidenceNeutron("TC_n","Triple Coincidence (e,e'pn)","SK","NA");
gHaPhysics->Add( TC_n );
Thus the block TC_n.* must be added to the .odef file to display the associated variables.
These variables are:
TC_n.pn_x_l x-comp of Pn in the lab [Pn = -Pi = -(P - q)] TC_n.pn_y_l y-comp TC_n.pn_z_l z-comp TC_n.pn_x x-comp of Pn in the ND frame TC_n.pn_y y-comp TC_n.pn_z z-comp TC_n.pn magnitude of Pn TC_n.angle cos of the angle between Pn and the "best" track TC_n.ntof TOF of neutron for the "best" track TC_n.nphi phi TC_n.ntheta theta TC_n.nenergy energy deposit TC_n.nnhits number of bars hit by the "best" track
Note that the track variables are no longer arrays, since a "best" track has been selected.
There is no evidence yet that this approach is valid on 12C. Needs to be tried.
The libBigbite library has been updated on the adaq machine, but none of
the physics*.C files, as I don't know which ones people uses.
