//
// Thrust Major (TM) analysis of reconstructed jets.
// TM is the thrust in the plane perpendicular to the jet axis
// The present amalysis performs the following steps:
// (a) Construct to orthogonal unit vectors (e1, e2) in the plane perpendicular to the jet axis
// (b) Calculate the components of all particles with jT > 1 GeV with respect to e1, e2
// (c) Construct the sphericity matrix
// (d) Find the two orthogonal eigenvectors of the spericity matrix
// (e) Caluclate the components of all particles with jT < 1 GeV in the reference frame spanned by the eigenvectors
// (f) Calculate the azimuthal angle in this frame
//
