The Broad Emission Line MApping Code (BELMAC; Rosborough et al., 2024 & 2025) simulates the velocity-resolved reverberation response for any broad emission line by incorporating photoionization model grids.  The photoionization models are pre-computed using Cloudy v23 (Gunasekera et al., 2023).  BELMAC can be used for simulating and modeling reverberation responses, single-epoch spectra.  For modeling data, BELMAC uses either dynesty (nested sampling) or RIFT-HyperPipe (Monte Carlo) wrapper, for HPRC and HTC clusters, respectively.
