### new power spectrum new parameters

Dear all
I have calculated this new power spectrum:

$P=A_{s}\big(\frac{k}{k_{\star}}\big)^{n_{s}-1}(1+\sigma(\frac{k}{k_{\star}})^{-\varepsilon}\cos(2/\sigma_{0} (\frac{k}{k_{\star}})^{\varepsilon}))$

where $\sigma$ and $\varepsilon$ are the new parameters. I want to use cosmomc for fitting data. I hope someone would reply to that which files must be changed?
I have also read the previous posts but I want to be sure about my work.
