Dear all:
Now I want to compute the CMBLSS crosscorrelation with CAMB.(i.e.<(\delta T / T)( \delta\rho/\rho)> .Any suggestions regarding the details when using CAMB ?
Cheers,

Re: CAMB:compute the CMBLSS crosscorrelation
The calculation is quite similar to the one CAMB does to compute the lensing potential power spectrum and its crosscorrelation to the temperature.
You can edit the output routine in equations.f90 to change the third scalar source term appropriately: some combination of the matter perturbation amplitude with a window defined by your LSS source distribution. Then if you run with lensing turned on, the output in the C_l file will be your new power spectra instead of the lensing ones.
