Cumulative explained variance ratios computed from the singular value decomposition of the Jacobian matrices for dimensionless l = 0, 1, 2 mode frequencies with respect to the nine candidate latent variables described in the main text. Different colors indicate values computed with respect to stellar models at fiducial radii of 1, 2, 3.5, and 6 R_⊙. In all other respects, these models are solar-calibrated. Since dimensionless frequencies are used in this calculation, and a combination of M and R sets the fundamental frequency for these normal modes via , one more degree of freedom must be considered than shown here for any given desired amount of variance to be explained.
