Hi.
I’m trying to turn off tight coupling, not second order tight coupling, but I couldn’t it.
I already know ‘second order tight coupling’ is logical and parameter statement in GaugeInterface.
Is it possible that turning off tight coupling in CAMB/equation.f90 ?

Any help would be appreciated.

You'd have to edit the code to do that. However note that the general equations become stiff, and the default integrator does not work well with stiff equations.

Thank you for replying!
