Did you read my explanation of this? Did you understand it? The eight Arizona measurements were not of eight different pieces of Shroud. They were measurements of four different pieces, each piece given two measurements. Why they submitted their measurements like this I can’t distinctly recall. I think it was because the little disc containing carbon samples from each piece was run through their apparatus twice, and all the measurements taken on each run combined into one measurement for each piece. The other two laboratories only ran each little disc though their machine once, so they could only produce one averaged result for each piece. For consistency, each of the twelve samples was represented in the Nature paper as a single measurement. There is nothing underhand about it; it would be entirely normal practice.Based on private correspondence with two scientists at Oxford and one at Arizona, chemist Remi Van Haelst states that the British Museum solved this problem [the 250 year variance] by asking Arizona to combine or essentially average the two radiocarbon sample ages from each of the four above dates … . The British Museum and the Arizona laboratory thus combined eight measurements into only four . … This combination was not mentioned in the official “NATURE” report containing the Shroud’s radiocarbon date of 1260-1390 with 95% certainty.
A much more thorough analysis was carried out by Riani, Atkinson et al., who, although they were forced to make some assumptions, also determined a radiocarbon concentration gradient along the sample.[Dr. Brian] Walsh states that his statistical analysis indicates leads to the conclusion that Shroud subsamples each contained differing levels of C-14. Furthermore, his analysis indicates that a relationship exists between the C-14 content within each sample and thier location on the cloth.
Oh, pur-lease. You didn’t read my explanation, and you haven’t read the Nature paper. That’s quite naughty of you.If Arizona’s two youngest ages of 540 and 574 weren’t completely eliminated from the [NATURE] report, this correlation would have been more obvious to everyone who read the report.
