According to Mathematica's Correlation function:
[Correlation](http://reference.wolfram.com/language/ref/Correlation.html)
1. Raw data correlation between Tahiti and Darwin data is 0.583649
2. But if both denoised by Daubechies [4] index {0,0,0,0} Correlation is -0.507138 a negative number
3. But if both denoised by Daubechies [4] index {0,0,1} Correlation is 0.911759 i.e. 12 month periodic part of the data
I checked the code and seems to be in order!
