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.
