Hi,
I am a little confused about the acl in the new cliklike.f90 module. When I print these acl's they have an awkward normalization (given that my priors are really tight). The first peak has an amplitude of 300, while in the old calk like.f90 the amplitude was equivalent to the standard normalization (~5500). What is the normalization of the new acl?
I have been modifying the code, but I set all new parameters to zero. If it should be the same I'll dig back into the code to make sure.
Thanks in advance

Re: acl in cliklike vs acl in calklike
They should be raw [tex]C_L = \langle |a_{LM}|^2\rangle[/tex] in [tex]\mu K^2[/tex], i.e. multiply by [tex]L(L+1)/2\pi[/tex] to get what is normally plotted. (300 for first peak doesn't sound quite right though)

Yes, sure, I meant l(l+1)acl/2pi. Let me check recompiling a clean version and adding a print statement. if it is different still I have done something wrong with adding the parameters.
thanks
