varaince and var_n jnl files

[Dr Sudheer Joseph <sjo@xxxxxxxxxxxxx>]

Dear Users,
                         Has any one used the varaince and var_n.jnl files 
suplied with ferret? 
http://ferret.pmel.noaa.gov/Ferret/FAQ/analysis/correlations.html. I am 
finding  correlation of the out put at the above link shows more than 1. how 
can this happen?, the correlation coefficient can only vary between -1 to +1 
which will happen when there is no correlation at all and when there is 100% 
correlation respectively. What is the method used in the jnl file? is it 
covariance instead of correlation?( but there is covariance under the same 
varaiblle name as out put) . Please help if any one has the answers.
Thanks in advance,

Sudheer
