CAMB - arbitrary power spectra
Posted: August 08 2006
Hello -
I am currently trying to modify CAMB to take in arbitrary power spectra, however, I am unsure of the best way to sample the k-space. A naive logarithmic sampling across the full range of k values causes CAMB to return incorrect CMB spectra. Also, given a prescription for k sampling, can one compute the dk vector by simply taking the difference between subsequent k values?
As I am very new to the software, any help would be greatly appreciated.
