Nordic Archaeological Abstracts

A list of Dendro-related archaeological abstracts are found on http://www.naa.dk/web-index-guests/search.cgi?find1=dendrokronologi&nationalitet=&tid= . Some of them may be of interest. For instance I just read an article in Fornvännen I did found this way, about the excavations of the prehis...

Re: Questions raised by the Hollstein data

Please also note that the uncertain years according to Holstein data detected by Lars-Åke are 207 years before approximately 540 AD (i.e aprox. the years 333-540 AD) which is an other period than Illig's "Phantom time" (7'th to 9'th cent AD). His needs of exactly 297 years after AD 590, ac...

Re: Using CDendro to analyze tree growth with climatic trends

Hi Sarah, Using the detrend function you need to be aware of its mechanism. It will just try to find a negative exponential shaped trend, and if finding one it will "straight" the actual curve according to that. If not it will instead divide each ring width just with the mean of them all. ...

How to select ALL samples with overlap >50 towards reference

I would like to know the correlation values for ALL samples in a collection where the overlap is at least 50 years, not only those with corr>0. How to do? (I need it to show how very bad a particular dating proposal really is!) The "Select best matching members"- function (a button availa...

Re: Test towards reference - how to understand?

I do agree with Lars-Åke. Just to clarify: The best match of the short "reference" (the undated sample here selected as reference) towards the mean of the whole collection is at 1918, and than CDendo assumes that as the right date for the "reference". The blank lines appears for ...

PCAB correlations towards PICE - Different patterns

Picea abies (PCAB) and Pinus cembra (PICE) – Is it possible to date samples from one of those species towards a chronology of the other? To answer this question I selected from ITRDB Pola020 (PCAB, 1500m, 49°15'N 19°55'E by F. Schweingruber) and Pola300 (PICE 1550m 49°14'N 20°00'E by Bednarz). They...

Violins of Scandinavian spruces?

I have asked a question to some people knowing a lot about violins, if there are any violins made of svandinavian spruce-wood. The common (and surely the right) answer is that according to tradition also Swedish instruments are made of central European wood, at least high quality instruments. It wou...

Re: Kubbhus

Om det Sörmländska kubbhuset var tillverkat av en gammal "lada": Antar att du kanske sågade ett tvärsnitt av kubben och har en bild kvar? Kanske du i så fall vill dela med dig av den, och se om man kan bli något klolare av det.... Om det är som jag tror så finns Bengt med i forumet, och då...
