This is a pdf file..
It shows graphs, etc. that explain the methodology used, and why it was invalid..
It also severely criticizes that method.. (see "discussion" at end of article.)
What is centering? Averaging the temperatures for a centerline on a graph or is it more involved?
Also what does this mean, MBH98 did not use archived data, but made an extrapolation, unique within the corpus of over 350 series, and misrepresented the start date of the series. ? Is he saying that they didnt have data for some important subsection of date ranges and made it up statistically and dishonesty?
It sounds like one confirming study used a poor choice of tree species and another did the above, making up holes in the data incorrectly.
I missed the criticism of the original study in the discussion section. Id dig into the heart of the study myself, but it would be a half day project for me, and I dont have that kind of time. If you dont have time either to translate, I understand. Regards.
