15 Assume given Pt versors of both reco jets
16 
17  R1(x1,y1)~Pt1
18  R2(x2,y2)~Pt2
19 where x1^2+y1^2=x2^2+y2^2=1
20 
21 All in fixed LAB refence frame.
22 
23 The magnitude of the angle we want is always:
24 
25 | delta phi | = pi - acos(x1*x2 + y1*y2)
26 
27 The sign if beam polarization is vertical.
28 
29 delta phi > 0 if x1+x2 > 0
30 delta phi < 0 if x1+x2 < 0
31 
32 Lets define also: <b> Delta phi</b>=pi+delta phi
33 
34 ====================================
35 Use of the table:
36 
37 float phi1=... //(rad), range [0,2Pi]
38 float phi2=... //(rad), range [0,2Pi]
39 
40 int kphi1=(int)(phi1*10.);
41 int kphi2=(int)(phi2*10.);
42 int kDelPhi=map_DelPhiJets[kphi1*MxPhiRad10 + kphi2];
43 // note, the order of phi1,phi2 does not matter
44 
45 float DelPhi=kDelPhi/10.; // again in radians, range [0,2pi]
46 float delPhi=DelPhi-pi; // if needed
