CAMB: vector modes

Post by Anze Slosar » October 28 2005

Is there any good reason why CAMB wouldn't do vector modes together with scalars and tensors? It barfs saying: "Must generate vector modes on their own"...

Just because I was lazy and didn't write vector versions of the power spectrum routines (partly also to make it backwards compatible with older power spectrum modules).

At the moment the vector code calls ScalarPower for the vector modes rather than defining a new set of routines -see GetInitPowerArrayVec in cmbmain.f90. Should be quite easy to change if need be.
