add cross-correlation functionality to accept CrossSpectrum objects?

[davis191]

Hi,

Currently, the cross-correlation function only accepts two lightcurve objects. It would help to have the option to have an Average/Crossspectrum object be a potential input as well.

Thanks @davis191, good suggestion. I don't personally know when I'll have the time to work on this, but if you and/or someone else come out with an implementation I can help adapting it to our code.

Where does one begin to implement it? Any details?

[matteobachetti]

Isn't the cross correlation just the inverse Fourier transform of the cross spectrum? If so, the implementation should be very straightforward. The relevant class is in stingray/crosscorrelation.py. We could modify the __init__ method to allow a cross spectrum object.

Yeah! It should be fairly simple. I can give it a go this afternoon!

Hi , has this issue been solved?
