Compute the probability that two functions are correlated at a given spherical harmonic degree for a given correlation coefficient.


prob = SHConfidence (l, corr)


prob : output, real*8
Probability that two functions expressed in spherical coefficients with spectral correlation corr are correlated at degree l.
l : input, integer
The spherical harmonic degree.
corr : input, real*8
The correlation coefficient of the two data sets at degree l.


SHConfidence will calculate the probability (between 0 and 1) that two sets of spherical harmonic coefficients with spectral correlation corr are linearly correlated at a given degree. This is calculated using equation A7 from Pauer et al. (2006).
