Gravelamps: Gravitational Wave Lensing Mass Profile Model Selection

Gravelamps is a package built upon the bilby parameter estimation framework designed to perform template based parameter estimation and model selection analyses of both simulated/injected and real gravitationally lensed gravitational wave signal data to determine the lens and source parameters of the signal as well as the lens mass density profile.

It is able to do this both in the wave and geometric optics regimes and may use both regimes inside of a single analysis to give a great deal of flexibility to the end user in regards speed vs completeness of calculation. The amplification factor code is written in the accompanying C++ libraries to give access to the arbitrary precision C library arb (part of FLINT). These are wrapped in the gravelamps.models module.
