Model Specific Options
======================

Each model in Gravelamps supports a number of potential options that can be
given as part of the INI. Models may also have specific requirements in order
to run correctly. This page will give the requirements for each model and
detail the options available for that model.

Isolated Point Mass
===================

Supported Options
-----------------

* ``extra_lens_keys``
    * ``geo_switch``
        Dimensionless frequency at which to switch to using the geometric
        optics approximation. Default when not passed is 1000.
    * ``precision``
        Precision to use for wave optics calculations. Default when not passed
        is 1000.

Singular Isothermal Sphere
==========================

Supported Options
-----------------

* ``extra_lens_keys``
    * ``summation_limit``
        Upper limit to use for the infinite summation in the wave optics
        calculation. Default when not passed is 4000.
    * ``geo_switch``
        Dimensionless frequency at which to switch to using the geometric
        optics approximation. Default when not passed is 600.
    * ``precision``
        Precision to use for wave optics calculations. Default when not passed
        is 6000.

Navarro Frenk White
===================

Required Options
-----------------

* ``extra_lens_keys``
    * ``scaling_constant``
        Characteristic scale of the NFW profile.

Supported Options
-----------------

* ``extra_lens_keys``
    * ``integration_limit``
        Upper limit to use for the infinite integration in the wave optics
        calculation. Default when not psased is 100.
    * ``geo_switch`` 
        Dimensionless frequency at which to switch to using the geometric
        optics approimation. Default when not passed is 1000.
    * ``precision``
        Precision to use for wave optics calculations. Default when not passed
        is 128.

Phenomenological Millilensing
=============================

Required Options
----------------

* ``no_conversion_to_dimensionless_frequency``
    Required to be set to ``True``.
* ``max_num_images``
    Maximum number of images to be set by the prior.

O3 Microlensing
===============

.. warning:: 
  The O3 Microlensing model is deprecated and may be removed in a future
   release.

Required Options
----------------

* ``lookup_table``
    Path to the lookuptable.h5 file.
