py21cmfast.wrapper.inputs.CosmoTables
=====================================

.. py:class:: py21cmfast.wrapper.inputs.CosmoTables

   
   Class for storing interpolation tables of cosmological functions (e.g. transfer functions, growth factor).

   :ivar transfer_density: Interpolation table for the density transfer function.
                           In InputParameters, becomes non-trivial only if MatterOptions.POWER_SPECTRUM is set to "CLASS".
   :vartype transfer_density: Table1D | None
   :ivar transfer_vcb: Interpolation table for the velocity transfer function.
                       In InputParameters, becomes non-trivial only if MatterOptions.POWER_SPECTRUM is set to "CLASS" and MatterOptions.V_CB_MODEL = "FLUCTS".
   :vartype transfer_vcb: Table1D | None
   :ivar USE_SIGMA_8: Flag to indicate whether to use CosmoParams.SIGMA_8 or CosmoParams.A_s for the normalization of the power spectrum.
   :vartype USE_SIGMA_8: bool | None
   :ivar ps_norm: Normalization factor for the power spectrum. If USE_SIGMA_8 is True, this is set to CosmoParams.SIGMA_8, otherwise it is set to CosmoParams.A_s.
   :vartype ps_norm: float | None
   :ivar V_CB_AVG: Mean value of the amplitude of the relative velocity between baryons and cold dark matter at kinematic decoupling, in km/s.
                   In InputParameters, becomes non-trivial only if MatterOptions.V_CB_MODEL is set to "AVG-AUTO".

   :vartype V_CB_AVG: float | None

   .. py:method:: new(x: dict | Self | None = None, **kwargs)
      :classmethod:


      
      Create a new instance of the struct.

      :Parameters: **x** (*dict | CosmoTables | None*) -- Initial values for the struct. If `x` is a dictionary, it should map field
                   names to their corresponding values. If `x` is an instance of this class,
                   its attributes will be used as initial values. If `x` is None, the
                   struct will be initialised with default values.

      :Other Parameters: * **All other parameters should be passed as if directly to the class constructor**
                         * **(i.e. as parameter names).**
