A nested sampling approach to quasi-stellar object (QSO) accretion disc fitting.
This repository contains a Python module for modelling accretion discs around astrophysical objects. The module provides functions to calculate physical quantities related to accretion disks and perform parameter estimation using observational data. The accretion disc model is the alpha-disc model (see Shakura & Sunyaev 1976), while the parameter estimation can be performed either with Nessai, Raynest or CPnest.
