Description
300s binned 2-8 keV Chandra light curves of Sgr A*. The event lists needed to produce these plots are obtained by reducing the raw data using standard CIAO tools. The extraction region is a small radius 1.25" circular region centered around the radio position of the Sgr A*. For gratings observations (from the X-ray Visionary Program (XVP)), we use 0th and +/- 1st order counts, with grating order tolerance of +/- 0.2. The first order counts are extracted from a rectangular box with a 5 pixel (2.5") width also centered on the source. The red horizontal lines are Bayesian Blocks calibrated on signal-free Poisson light curves with a false alarm probability, p0, of 5%. Their error bars are Poisson errors. Identified flares are isolated by blue vertical lines.
