.. _cmb: ### CMB ### To add in the CMB (either as something to observe, or a noise source), we add .. code-block:: python sim = maria.Simulation(instrument=my_instrument, site=my_site, plan=my_plan, atmosphere="2d", cmb="generate") We can customize the CMB by specifying a set of ``cmb_kwargs`` to, e.g., increase the resolution of the generated map. .. code-block:: python sim = maria.Simulation(instrument=my_instrument, site=my_site, plan=my_plan, atmosphere="2d", cmb="generate", cmb_kwargs={"nside": 4096})
