/* PROGRAM TRANSFERFUNCTION
|
||||
|
||||
--- transfnc(xk)
|
||||
--- compute the transfer function T(k) of the power spectrum
|
||||
--- T(k) defined as P(k) = k^{xindx}*T^{2}(k)
|
||||
|
||||
* itrans=type of transfer function
|
||||
0 -> no change (returns 1)
|
||||
4 -> Efstathiou, Bond & White transfer function with Gamma as
|
||||
specified (eqn. 7)
|
||||
5 -> Eisnstein & Hu
|
||||
11 -> read in TF from file (usually CMBFAST)
|
||||
|
||||
NOTE: xk is in h/Mpc and is defined as k=2pi/lambda (not k=1/lambda)
