We present the package Gravelamps which is designed to analyse lensedgravitational wave signals in order to constrain the mass density profile ofthe lensing object. Gravelamps does this via parameter estimation using theframework of bilby, which enables estimation of both the lens and the sourceparameters. The package can be used to study both microlensing and macrolensingcases -- where the lensing mass distribution is described by a point mass andextended mass density profile respectively -- and allows the user to easily andfreely switch between the full wave optics and approximate geometric opticsdescription. The performance of Gravelamps is demonstrated via simulatedanalysis of both mircolensing and macrolensing events, illustrating itscapability for both parameter estimation and model selection in the wave opticsand hybrid environments. To further demonstrate the utility of the package, thereal gravitational-wave event GW170809 was analysed using Gravelamps; thisevent was found to yield no strong evidence supporting the lensing hypothesis,consistent with previously published results.
