a problem with CAMB

[M Zarei]

Dear All


I want to have the gravitational potential [tex]\Phi[/tex] in terms of "k".
I know how to modify the CAMB to draw the [tex]\Phi[/tex] in terms of scale factor
"a" and also know how to change the range of "a".
I also know how to derive the potential [tex]\Phi[/tex] in terms of "k" using CAMB.
But my problem is that whatever I try to change the range of "k" and the
number of mesh-points, I can't do it. Could you please write to me how I can
do this modification?

Thanks a lot in advance

You could write it out with the matter transfer functions (outtransf in equations.f90). You can easily re-spline any given output table, or you can change the lnk spacing CAMB uses for outputting the matter power function and transfer functions.
