What Are the Margins of Error in Calculating the Cosmologic Constant?

This paper is 50 pages, and gives a good historical overview for the
CC problem, It also looks into the contributing aspects for CC calculation,
red shift, CMBR , quasars etc.
It also shows that a margin for error is possible in most if not all attempts to
calculate the CC.
If everything in this paper is taken into consideration along with other
publications, What is the best fit for a CC and what are the margins
of error?

The paper is very complete, with historical explanations, that I always enjoy, but more or less I am familiar with the concepts explained; perhaps the only thing that I hahdn't heard about before is the concept of Boltzmann hierarchy
Keep posting interesting papers, wolram
