Since the day the first Wilkinson Microwave Anisotropy Probe (WMAP) data were released, in 2003, all manner of cosmic microwave background (CMB) anomalies have been reported; there's been the cold spot that might be a window into a parallel universe, the "Axis of Evil", pawprints of local interstellar neutral hydrogen, and much, much more.But do [...]

With six free parameters and liberal pixel temperature corrections, it is not surprising the revised AlphaCDM model emerged either.

Don't you mean LCDM (Lambda, Λ), Jerry?

And the pixel temperature corrections (whatever you might think they are) were rigorous, not liberal, as the Sky Maps, Systematic Errors, and Basic Results paper makes clear.
