/* ** ** 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 59310.243295 0.000764 0.17707 0.03452 0.76136 0 2.58947 0.23217 2.07640 0.18619 0.45851 0.07938 0.36782 0.06366 59310.244542 0.000477 0.14000 0.03901 0.72121 0 2.65347 0.28786 2.13766 0.23201 0.37148 0.09535 0.29761 0.07641 59310.245569 0.000544 0.21546 0.05156 0.71719 0 2.16351 0.25613 1.73761 0.20567 0.46616 0.09693 0.37434 0.07787 59310.246771 0.000639 0.36687 0.09953 0.61364 1 1.83822 0.22979 0.75071 0.09384 0.67438 0.16237 0.27585 0.06642 59310.248470 0.001060 0.22049 0.05752 0.68493 1 1.66369 0.17494 0.68290 0.07178 0.36682 0.08758 0.15012 0.03586 59310.251491 0.001961 0.22325 0.04291 0.57481 1 1.85107 0.13844 0.75785 0.05667 0.41326 0.07316 0.17002 0.03009
