How to get Cl data covariance matrix from Planck Data

Hi All,

I am curious if it is possible to get the Cl data covariance matrix from PLANCK (with different combinations of data set). I have downloaded Planck Likelihood code plc-3.01 with CLIK data. The example provided in the package only tells me how to get the likelihood. My GREP search suggests a couple of modules which may be useful but without any examples it would be very difficult for me to start from the beginning.

Any suggestions or guideline would be highly appreciated.
