Is there a way to adjust the semi-major axis 'a' of the orbit in the model?

Hello,

I am trying to adjust the mean flux received from the Sun on Earth, there are two methods I am thinking of.

The first one is to increase or decrease the semi-major axis 'a' which essentially changes the flux;

For the second one, I could scale up/down the total luminosity of the Sun knowing that we can redefine the spectrum in the user_nl_cam/user_nl_cpl namelists.

Does anyone know if it is possible to change the semi-major axis 'a' in the model, any hint is appreciated.

Thanks in advance.
