We apply the Proper Orthogonal Decomposition, a method used to obtain information about coherent structures in turbulent fields, to the photospheric vertical velocity field obtained through the data acquired by the THEMIS telescope. We found that four modes are nearly sufficient to reconstruct both the granulation field and the p-modes.

Abstract
We apply the Proper Orthogonal Decomposition, a method used to obtain information about coherent structures in turbulent fields, to the photospheric vertical velocity field obtained through the data acquired by the THEMIS telescope. We found that four modes are nearly sufficient to reconstruct both the granulation field and the p-modes.File in questo prodotto:
