modifying the CLASS code in synchronous gauge #417
I want to study the properties of a modified gravity model in which the field equations are different from general relativity (in background and perturbative level). I have modified the CLASS code only in synchronous gauge (ignoring all the transformations of \Phi and \Psi to h and \eta, because the previous relations for transforming between two gauges in not valid in this new model), and I want to know if I would get correct results for CMB (include lensing) and matter power spectra diagrams in this way, or should I modify relations for \Phi and \Psi too?
Thanks
