CL) at 150GHz. The SPT and ACT power spectra and resulting constraints on SZ power are consistent within the reported uncertainties. On much larger angular scales ($\ell \le 2000$), the [[*Planck*]{}]{} collaboration has detected the tSZ power spectrum at high significance [@planck13-21]. The measured tSZ power at all scales is less than predicted by some models, suggesting either current astrophysical models over-predict the tSZ power or that $\sigma_8$ is significantly less than the value of $\sim$0.8-0.83 preferred by [[*WMAP*]{}]{} and [[*Planck*]{}]{} analyses of primary CMB anisotropy [@hinshaw13; @planck13-16].

The tSZ power has also been detected in higher-order moments of maps using data from ACT [@wilson12] and SPT [@crawford14] (hereafter C14). Including an 11% modeling uncertainty, C14 use the measurement of the bispectrum to predict the tSZ power to be $D^{\rm tSZ}_{3000} = 2.96\pm0.64\,\mu{\rm K}^2$ at 153GHz. The results are consistent with the direct power measurements.

The same data used to measure the SZ power spectrum can also be used to measure the CIB power at millimeter wavelengths and, if multi-frequency data are available, the CIB spectral behavior at these wavelengths. In previous work, the data lacked statistical power to test the need for separate spectral indices for the Poisson and
