Description
We perform a Principal Component Analysis (PCA) of $v_3(p_T)$ in
event-by-event hydrodynamic simulations of Pb+Pb collisions at the LHC. We
show that factorization matrix $r_3(p_{T1},p_{T2})$ can be economically
presented in terms of two dominant principal components of the two
particle correlation function. We find that the subleading flow is
predominantly a response to the radial excitations of third order eccentricity. We
present a systematic study of the hydrodynamic response to these radial
excitations in 2+1D viscous hydrodynamics. Finally, we construct a good
geometrical predictor for the orientation angle and magnitude of the leading
and subleading flows using two Fourier modes of the initial geometry.
