System Description
##################

The first set of parameters which SIROCCO needs are information about the overall system.

.. code::
   
   System_type(star,cv,bh,agn,previous)                   bh

   ### Parameters for the Central Object

   Central_object.radiation(yes,no)                  yes
   Central_object.rad_type_to_make_wind(bb,models,power,cloudy,brems,mono)                power
   Central_object.luminosity(ergs/s)          4.72063e+37
   Central_object.power_law_index                 -1.5
   Central_object.geometry_for_source(sphere,lamp_post,bubble)               sphere

:ref:`System_type` is starting point, a basic classification of the type of object one is trying to model.
This is used to guide further questions about the object and to set defaults.

Most of the other parameters are fairly self-explanatory, and are documented fully in the various :ref:`Parameters` entries.
