Re: Multi-radii cross correlation

I am building a chronology from living trees based on a big number of trees (>100 per species). I do have 4 radii from each of them. So when i do a cross correlation to see which are best match, radii from the same trees always match up even if the sum by stem button is checked. It would be lot of ...

Re: The development (test) version of CooRecorder

I have updated CooRecorder a little to make it more easy to collect curvedata: http://www.cybis.se/forfun/dendro/curvetowidth/pic/connectpoints.gif Also, when there are multiple curves (e.g. two) in the same diagram, it is now possible to set out labels in CooRecorder at e.g. a certain year in both ...

How to see the year number of a certain ring

In response to a request from Igor Drobyshev, there is now a mechanism which makes it possible to see the corresponding year number for a certain ring. This is useful when you know of some pointer years - known to be related to very thin or very wide rings - and you want to see which rings they corr...

Re: The Development version of CDendro

There is now still another new development version of CDendro - this time named CDendro 7.2 - available for download and testing. Various detrending and normalization methods have been added to the program during a long time. I have now rewritten these methods so they are all handled in the same way...

Fooled by the normalization method and some narrow rings

While analyzing the data in the file CO20050101-LCE-AjC.txt at the French CNRS database I observed a number of quite high Baillie/Pilcher and Hollstein based TTest correlation values which were not considered as correct datings. An analysis revealed that it was caused by a combination of VERY narrow...

Re: CNRS Database

Hi Ale and everybody! I've now looked into the Besancon files again. I think I can program a read-in mechanism for these files without getting further information. Of course it would be fine to know more, though many examples are usually the best way to go. About Becanson normalization: The filter o...
