Dear Antony Lewis,

can you tell me, what I have to do to get the radiation transfer function T_l(k) from the CAMB-code and how is it defined there, like equation (6.197) in your dissertation?

Best wishes,

Sven Lustig

If you look in CAMB.f90 you'll see the subroutine CAMB_GetTransfers taht you can call do get the C_l transfer functions. The routine CAMB_TransfersToPowers(CData) shows how you then go from the transfer functions to the power spectrum.

ComoMC is an example of a program which gets the transfer functions from CAMB this way. I think the code is the same as my thesis to with a possible constant numerical factor (like 1/4).
