/* ** ** 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 58231.968230 0.000886 0.28992 0.07385 0.70492 1 1.39858 0.16315 0.65230 0.07612 0.40548 0.09181 0.18845 0.04268 58231.969973 0.000857 0.27458 0.06952 0.66102 1 1.55358 0.16865 0.73169 0.07942 0.42658 0.09757 0.20069 0.04590 58231.971745 0.000915 0.23462 0.06025 0.66667 1 1.65298 0.17758 0.78100 0.08388 0.38782 0.09047 0.18283 0.04264 58231.974026 0.001365 0.19299 0.04746 0.59574 1 1.53148 0.13844 0.72441 0.06548 0.29556 0.06759 0.13977 0.03197 58231.976640 0.001220 0.25188 0.06317 0.53571 1 1.45328 0.14214 0.68245 0.06674 0.36605 0.08454 0.17229 0.03979 58231.979197 0.001307 0.23190 0.05339 0.64444 1 1.46482 0.13346 0.69106 0.06294 0.33969 0.07182 0.15998 0.03382
