Info
----

Calculates an incoherent scatter radar spectrum based on the theory presented in
`Hagfors (1961)`_ and `Mace (2003)`_.

Installing
----------

You can install *inscar* via pip_ from PyPI_:

.. code:: console

   $ pip install inscar

Usage
-----

Please see the `Modules Reference <Modules_>`_ for details.

Numba
^^^^^

Faster integration is accomplished by computing in parallel. This is
accomplished using `numba`.

Physical environment
^^^^^^^^^^^^^^^^^^^^

The available plasma parameters that can be changed within the program are

.. code:: text

    === Input parameters ===
    K_RADAR -- Radar wavenumber (= -4pi(radar frequency)/(speed of light)) [m^(-1)]
    B -- Magnetic field strength [T]
    MI -- Ion mass in atomic mass units [u]
    NE -- Electron number density [m^(-3)]
    NU_E -- Electron collision frequency [Hz]
    NU_I -- Ion collision frequency [Hz]
    T_E -- Electron temperature [K]
    T_I -- Ion temperature [K]
    T_ES -- Temperature of suprathermal electrons in the gauss_shell VDF [K] (no longer in use)
    THETA -- Aspect angle [1]
    Z -- Height used for calculated distribution [100, 599] [km]
    mat_file -- Time of day for calculated distribution
    pitch_angle -- Pitch angle for calculated distribution

Calculation method
^^^^^^^^^^^^^^^^^^

The program support different methods of calculating the spectrum, based on how you
assume the particles to be distributed. This includes a Maxwellian distribution and a
kappa distribution, in addition to any arbitrary isotropic distribution.
