A 2500 deg<sup>2</sup> CMB Lensing Map from Combined South Pole Telescope and Planck Data
Abstract We present a cosmic microwave background (CMB) lensing map produced from a linear combination of South Pole Telescope (SPT) and Planck temperature data. The 150 GHz temperature data from the 2500 deg 2 SPT-SZ survey is combined with the Planck 143 GHz data in harmonic space to obtain a …
