/* ** ** 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 55297.294051 0.000666 0.21199 0.03826 0.76957 0 2.77939 0.22802 2.38758 0.19590 0.58921 0.09472 0.50502 0.08118 55297.295981 0.001259 0.18444 0.02461 0.75656 0 2.84324 0.16730 2.45177 0.14429 0.52441 0.06280 0.45188 0.05411 55297.360809 0.000498 0.11783 0.03151 0.75000 0 2.75160 0.25730 2.37690 0.22228 0.32423 0.08122 0.28085 0.07036 55297.361900 0.000593 0.23586 0.04136 0.80000 0 2.78424 0.23459 2.40643 0.20273 0.65670 0.10099 0.56732 0.08721 55297.363086 0.000593 0.21103 0.03806 0.83415 0 2.90463 0.24700 2.49827 0.21241 0.61297 0.09749 0.52806 0.08395 55297.364250 0.000570 0.25788 0.04579 0.76650 0 2.74380 0.23384 2.35615 0.20081 0.70756 0.11023 0.60890 0.09486 55297.365181 0.000362 0.17171 0.04493 0.84800 0 2.50836 0.28584 2.16426 0.24667 0.43070 0.10146 0.37103 0.08738 55297.366151 0.000608 0.25161 0.04537 0.75714 0 2.62532 0.22827 2.26923 0.19734 0.66056 0.10434 0.57137 0.09022 55297.367418 0.000660 0.24170 0.04153 0.75439 0 2.68793 0.22506 2.31575 0.19388 0.64967 0.09749 0.55895 0.08385 55297.368758 0.000668 0.22557 0.04024 0.73593 0 2.74306 0.22219 2.36449 0.19143 0.61875 0.09836 0.53117 0.08444 55297.370071 0.000645 0.20084 0.03382 0.82960 0 2.99594 0.23622 2.56383 0.20221 0.60169 0.08952 0.51774 0.07703 55297.371353 0.000631 0.20660 0.03649 0.78899 0 2.99591 0.23684 2.55726 0.20226 0.61894 0.09774 0.52818 0.08340 55297.372765 0.000781 0.18912 0.03349 0.71481 0 2.84137 0.20892 2.42735 0.17860 0.53735 0.08657 0.46219 0.07449 55297.374232 0.000686 0.18428 0.03327 0.79325 0 2.98913 0.22948 2.55084 0.19589 0.55085 0.09002 0.46865 0.07658 55297.375711 0.000793 0.20509 0.03481 0.73358 0 2.70097 0.21069 2.29844 0.17933 0.55395 0.08349 0.47107 0.07100 55297.377233 0.000723 0.21809 0.03730 0.73600 0 2.73139 0.21566 2.34861 0.18539 0.59568 0.09037 0.51161 0.07762 55297.378749 0.000793 0.20119 0.03215 0.79197 0 2.94568 0.21588 2.50154 0.18337 0.59264 0.08414 0.50426 0.07163
