# Planck Cosmic Microwave Background Temperature Angular Power Spectra

X axis: $\ell$
Y axis: $\ell(\ell+1)/2\pi [\mu K^2]$

Power spectra from the 1st Planck Public data release

• Combined and channels spectra in FITS format available on the release website
• Best fit power spectrum Planck+WP+highL+lensing: Planck low and high-L Temperature with lensing reconstruction, low-L WMAP9 Polarization and high-resolution CMB datasets
• HFI power spectra were binned with a weighting proportional to $\ell$
• WMAP 9 year spectrum is unbinned until $\ell$ = 47, then binned for larger $\ell$, to be more easily compared to the Planck combined spectrum
