SL-Hammocks

SL-Hammocks is a Python code to generate mock catalogs of gravitationally lensed quasars and supernovae through a halo-model-based approach. The name is an acronym for Strong Lensing HAlo Model-based MOCK catalogS. This is the code developed as part of an LSST DESC project.

Requirement

This code uses glafic as a lens equation solver and Colossus for computations related to cosmology and dark matter halos. Other required installations include joblib for parallel computing, numpy and scipy for basic numerical computations. These Python modules need to be installed before running this code.

Examples

The full (1 realization) LSST quasar lens mock catalog is generated by python gen_mock_halo.py --area=20000.0 --ilim=23.3 --zlmax=3.0 --source=qso --prefix=qso_mock --solver=glafic --nworker=1 The full (1 realization) LSST supernova lens mock catalog is generated by python gen_mock_halo.py --area=50000.0 --ilim=22.6 --zlmax=2.0 --source=sn --prefix=sne_mock --solver=glafic --nworker=1

Output files

See output.txt for some explanations. You can download several examples of mock catalogs that are the output of this code in the data_public repository of LSST.
