The Planck cosmic microwave background temperature data are best fit with a ΛCDM model that mildly contradicts constraints from other cosmological probes. The South Pole Telescope (SPT) 2540 SPT-SZ survey offers measurements on sub-degree angular scales (multipoles ) with sufficient precision to use...
