/* ** ** Swift/XRT hardness ratio for M87. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 54510.173801 0.000703 0.20359 0.03531 0.76955 0 2.83242 0.23085 2.44696 0.19941 0.57665 0.08829 0.49916 0.07643 54510.175092 0.000576 0.27457 0.05102 0.76884 0 2.49683 0.23934 2.14416 0.20551 0.68555 0.10913 0.58950 0.09379 54510.176547 0.000874 0.21867 0.03453 0.73150 0 2.75752 0.20373 2.36979 0.17501 0.60298 0.08414 0.51710 0.07215 54510.210777 0.033341 0.36994 0.07086 0.01960 1 4.02137 0.36051 0.95575 0.08547 1.48767 0.25180 0.35126 0.05929 54510.242093 0.001172 0.21817 0.03351 0.72417 0 2.45070 0.18122 1.96772 0.14551 0.53466 0.07199 0.43006 0.05789 54510.244960 0.000842 0.30335 0.06621 0.69445 1 4.24778 0.42345 0.95929 0.09560 1.28856 0.25019 0.29068 0.05644
