Analyzing X-ray Variability by Linear State Space Models

摘要: In recent years, autoregressive models have had a profound impact on the description of astronomical time series as observation stochastic process. However, it has to be taken into account that real data always contain observational noise often obscuring intrinsic object. We apply technique Linear State Space Model which explicitly and allows estimate hidden As an example, we analysed X-ray flux variability Active Galaxy NGC 5506 observed with EXOSAT.
