it is an update, as of year-end 2005, of the best estimates of the values of the main cosmological parameters

like the Hubble parameter

and the dark energy density (or cosm. const.)

and the Omega number which is used to indicate how close to being spatially flat the universe is.

AFAIK there are no surprises here, the Hubble parameter is still 73 km/s per Megaparsec, and so on. but here it is if you want an up-to-date reference on the basic numbers
