- find sx3 events, gainmatch them, calibrate, make a vector of these called SX3_Events - same step for QQQ, call it QQQ_Events - find anodeWire clusters, cathodeWire clusters, make vectors of these - make PC_Events from wire clusters, save 'anode only' and 'cathode only' cases just in case * since PC_Events, QQQ_Events, SX3_Events are all STL containers, we can pass them to functions that perform modular analyses * In this commit: - 4-wire offsets used, along with reliably figuring out phi-offset between QQQ/SX3/PC. We are close, except for some QQQ fine-tuning due to their angular extent not being 90 deg - the pczfix step now makes sense, 1-wire calculations also loosely match between guess and pcz - the nonlinearity correction/dynamic range fix is just adding to the resolution - p(a,a) data analysable by QQQ alphas show good kinematics, when doing the following gates: > A1C1 event pczs dithered, A1C2 events made into pczfix > phicut (45 deg) to gate out p+a correlations, SiE < 5 MeV && PCa > 6000 to select the alpha blob in p+a > Some selection on VertexReconXY so that the Perp() of the vertex is < 6mm > Selection on VertexReconZ so that z is in [-173.6, 100]. Fine alignment pending - Doing all the above gives reasonable p(a,a) kinematic curves with good statistics, Ex peaked at -0.7 MeV, close but not perfect - The above steps, when repeated with oneWire anode events stored in aClusters also yields a very reasonable kinematic locus, and Ex value, even more statistics - Not sure how much of this is autocorrelation stuff but > VertexReconZ vs Ef in QQQ (Ef is eloss-fixed alpha energy using path length) shows sensible trends. - Why Ex is not centered around zero might need more thought. - VertexReconXY is suspiciously well-centered, might need some more thought as well. * Some infrastructure that allows processing of 17F data is also in the pipeline now. * One fairly important bug got fixed which was ignoring qqq.id[0] when making QQQ_Events * Ideally, follow-ups to the above done on 27Al, 17F will make their own functions that are then called separately using booleans at the very top. * The fate of proton dE signals is out to jury.
