/* ** ** 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 55296.357340 0.000402 0.15900 0.04055 0.76259 0 2.86087 0.30809 2.39362 0.25774 0.45487 0.10516 0.37731 0.08716 55296.358367 0.000625 0.26349 0.04826 0.77778 0 2.48319 0.24657 2.09695 0.20827 0.65430 0.10069 0.55299 0.08511 55296.359675 0.000683 0.23026 0.04129 0.77542 0 2.62004 0.22738 2.18670 0.18981 0.60329 0.09467 0.50443 0.07915 55296.361139 0.000781 0.20591 0.03662 0.75185 0 2.61742 0.21934 2.18399 0.18304 0.53895 0.08453 0.44998 0.07057 55296.362615 0.000694 0.21427 0.03865 0.77083 0 2.70928 0.23116 2.27054 0.19369 0.58053 0.09227 0.48815 0.07754 55296.363929 0.000619 0.26861 0.05109 0.73364 0 2.50034 0.24953 2.10456 0.20998 0.67161 0.10874 0.56529 0.09155 55296.365291 0.000744 0.23139 0.04280 0.75097 0 2.37178 0.22018 2.00934 0.18653 0.54881 0.08779 0.46523 0.07438 55296.366860 0.000825 0.24373 0.04190 0.69825 0 2.37918 0.20630 2.00325 0.17364 0.57987 0.08608 0.48734 0.07236 55296.368370 0.000686 0.23642 0.04170 0.73840 0 2.74333 0.23966 2.30408 0.20126 0.64858 0.09939 0.54487 0.08345 55296.369753 0.000692 0.21645 0.03863 0.76151 0 2.77828 0.23611 2.33044 0.19809 0.60135 0.09439 0.50720 0.07958 55296.371151 0.000706 0.25068 0.04410 0.70082 0 2.58053 0.22430 2.18133 0.18958 0.64690 0.09893 0.54632 0.08356 55296.372670 0.000807 0.22659 0.03957 0.70609 0 2.48056 0.20904 2.09082 0.17620 0.56207 0.08597 0.47422 0.07253 55296.374241 0.000758 0.20864 0.03759 0.76718 0 2.55366 0.22153 2.16450 0.18775 0.53281 0.08412 0.45187 0.07132 55296.375563 0.000564 0.27138 0.04955 0.77436 0 2.66333 0.25753 2.25336 0.21790 0.72278 0.11193 0.61181 0.09475 55296.376764 0.000631 0.23050 0.04349 0.75229 0 2.71557 0.24757 2.30655 0.21028 0.62595 0.10338 0.53167 0.08781 55296.378735 0.001340 0.20682 0.02771 0.73434 0 2.64633 0.15821 2.22299 0.13288 0.54732 0.06562 0.46094 0.05528
