[AstroPy] specutils.analysis.correlation

[Peter Dzwig]

Can people clear up a few points for me on this.

(i) Is specutils.analysis.correlation just scipy's correlation adapted 
to handle Spectrum1Ds;

(ii) Does it require the two input spectra to have been resampled before 
input, or is *all* necessary resampling done internally;

(iii) what technique is used for calculating the correlations?

I am trying to compare this to another approach and I can't find 
sufficient detail in the docs for what I need.

Many thanks,

Peter
