Bayesian Poisson Structure Function estimation
This project provides code (python script SF.py) to determine the X-ray Structure Function of a population of Active Galactic Nuclei (AGN) for which two epoch X-ray observations are available and are separated by rest frame time interval…
Ensemble Bayesian Excess Variance (eBExVar)
This project provides code (python script ebexvar.py) to determine the ensemble normalised excess variance of a population of Active Galactic Nuclei (AGN) for which multiepoch (X-ray) light curves of Poisson photon counts are available…
AGN Ensemble Variability Empirical Model
This project provides routines to model the ensemble excess variance of AGN using as input emprical relations and quantities. These inlcude the stellar mass function of galaxies, the specific accretion-rate distribution of AGN, the…
Bayesian X-ray/UV correlation estimator
Here we provide the data sample and main code used for the paper “Revisiting the X-ray–to–UV relation of Quasars in the era of all-sky surveys” by Chira et al. to reproduce the main results of the paper, in the spirit of the FAIR principles…
