Description: bexvar
        ==================
        
        Bayesian excess variance for Poisson data time series with backgrounds.
        Excess variance is over-dispersion beyond the observational poisson noise,
        caused by an astrophysical source.

        Introduction
        -------------------
        
        In high-energy astrophysics, the analysis of photon count time series
        is common. Examples include the detection of gamma-ray bursts,
        periodicity searches in pulsars, or the characterisation of
        damped random walk-like accretion in the X-ray emission of
        active galactic nuclei.
        
        Methods
        --------------
        
        This repository provides statistical analysis methods, which can deal with
        
         * very low count statistics (0 or a few counts per time bin)
         * backgrounds, which may vary as well, measured simultaneously in an 'off' region.
        
        The tools analyse eROSITA light curves. Contributions that can read other
        file formats are welcome.
        
        The bexvar_ero.py tool computes posterior distributions on the Bayesian excess variance,
        and source count rate.
        
        quick_ero.py computes simpler statistics, including Bayesian blocks,
        fraction variance, the normalised excess variance, and 
        the amplitude maximum deviation statistics.
