### Radiation transfer functions in CMB(CAMB)

Hi,
Can anyone tell how to get the radiation transfer functions for all l's using CAMB? I know it's been already posted, but I would really appreciate if one can explain it in detail how to modify codes to get them?

Thank you!

$\Delta_l(k)=$radiation transfer function in
$C_l =4\pi\int d\ln k P_{\chi}\Delta_l(k)^2$
