Inverse of the quality function of the period fit considering ℓ = 1 versus T_eff for SDSS J0349−0059, adopting the sets of 10 (left panel) and 11 (right panel) periods (see text for details). The vertical gray strip depicts the spectroscopic T_eff of SDSS J0349−0059 and its uncertainties. For clarity, the curves have been arbitrarily shifted upward (with a step of 0.05 in the left panel and 0.1 in the right panel) except for the lowest curve. The asteroseismological model has M_⋆ = 0.542 M_⊙.
