Hi,
when I select in params.ini the magnetic vector mode,
there are no evident options for selecting an amplitude and spectral index for the
magnetic part. Am I missing something or the default option in CAMB corresponds to
fixed values for these parameters, following the notation of
A. Lewis " CMB anisotropies from primordial inhomogeneus magnetic fields"(2004)?
Cheers
Daniela

It re-interprets the scalar mode settings as vector mode settings when you turn on vector C_l.
