Any muons with $p_\perp > 0.5$ GeV are found and projected onto many different observables. To restrict attention to direct/prompt electrons only, use the DIRECT option. To use lepton dressing, use the DRESSED option; this only makes sense for prompt leptons, and is automatically activated if DIRECT=1 is used, hence the main use of DRESSED is to *disable* lepton dressing in DIRECT=1 mode.
