I have recently updated several sections at http://www.cybis.se/forfun/dendro.
There is now also a new section http://www.cybis.se/forfun/dendro/detrendandnormalize/index.htm on Detrending, Normalization, Discrimination and Autocorrelation.
Edit April 2016: For CooRecorder bluechannel information, see http://www.cybis.se/forfun/dendro/helpcoorecorder7. There are several sections under the heading "On blue calibration".
