Left: one of the CMB maps, constructed using SEVEM (given at Nside = 64). Other Planck CMB maps are Commander-Ruler, NILC and SMICA, in addition to clean SEVEM maps from 44 to 353 GHz. Right: Planck lensing map, optimally filtered to perform the ISW–lensing cross-correlation (given at Nside = 1024). See Planck Collaboration XII (2014) and Planck Collaboration XVII (2014) for a detailed description of these maps.
