Logarithmic opacity derivative with respect to temperature for ATOMIC and OPAL tables with Z = 0.01, X = 0.80, and log R = −1.5. The larger gradients for the ATOMIC table opacities at the convection-zone base (log T = 6.3) and at ∼0.2–0.3 ﹩{R}_{\odot }﹩ (log T ∼ 6.8) in the solar interior are responsible for the differences in sound-speed gradients between models seen in Figure 4.
