1. Black hole Accretion Disc Fitting (BADFit)
   Samuel Lai
   Provides a Bayesian framework to model the large-scale multi-wavelength quasar spectral energy distribution with ray-traced thin and slim accretion disc synthetic spectra in order to constrain black hole properties.
2. Python-based Quasar Spectral Fit (PyQSpecFit)
   Samuel Lai
   Sensibly model emission features in rest-frame optical and ultraviolet quasar spectra using Levenberg-Marquardt algorithm.
