I reading article "The Cosmological Constant and Dark Energy" P. J. E. Peebles, Bharat Ratra http://arxiv.org/abs/astro-ph/0207347(adsbygoogle = window.adsbygoogle || []).push({});

They use following sources of density:

## \Omega_{M0}+\Omega_{R0}+\Omega_{\Lambda0}+\Omega_{K0}=1##

Next I see "

The measurements agree with the

relativistic cosmological model with

##\Omega_{K0}=0##, meaning no space curvature, and

##\Omega_{\Lambda0} ∼ 0.7##, meaning nonzero ##\Lambda##. A model with

##\Omega_{\Lambda0} = 0## is two or three standard deviations off the best fit, depending on the data set and analysis

technique.

"

Looked at referenced articles, not found where comes "two or three standard deviations off the best fit".

Is any paper with good analysis of different models and with calculations of deviations for best fit?
