Caption: Fig. 9.

Same as Fig. 7, but now with a spectral tilt of ﹩n=0.90﹩. The best fit has ﹩\chi ^{2}=17.8﹩. The primary effect is a shift to larger Ωmh2, ﹩0.143\pm 0.011﹩. However, this shift occurs at essentially constant R0.35; we find ﹩0.0986\pm 0.0041﹩. Again, the acoustic scale robustly determines the distance, even though the spectral tilt biases the measurement of the equality scale.
