CAMB: low-k in transfer function at high z

Post by Adam Hincks » June 03 2015

At z above about 1600, the minimum k-value for the output transfer functions is 0.554. How can I lower it? (Running January 2015 version.)

The transfer function outputs are only calculated once they contribute to observables. If you want to output the full evolution set fixq (defined in cmbmain.f90) to the k of interest, and then edit the corresponding write-out code in CalcScalarSources of cmbmain.f90.
