It swims particles through detectors taking into account magnetic fields, multiple scattering and dE/dx energy loss. It simulates parameterized showers in EM and hadronic calorimeters and supports gamma conversions and decays. In addition to three built-in detector configurations, detector descriptions can also be read from files in the new GODL file format.10 pages, 4 figures, presented at the Linear Collider Workshop LCWS'05, Stanford, CA, March 2005Instrumentation and DetectorsFast Detector Simulation Using Lelaps, Detector Descriptions in GODLtext
