/* ** ** 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 55197.061784 0.001641 0.23846 0.05806 0.98230 1 0.86034 0.09281 0.31559 0.03403 0.20516 0.04478 0.07567 0.01651 55197.064486 0.001060 0.24413 0.06246 1.00000 1 1.24099 0.15394 0.44511 0.05506 0.30296 0.06778 0.10959 0.02450 55197.067478 0.001932 0.20663 0.04648 0.83218 1 1.13853 0.10760 0.41994 0.03968 0.23525 0.04803 0.08673 0.01770 55197.134082 0.002411 0.15847 0.03443 0.92671 1 1.23472 0.10457 0.41079 0.03479 0.19567 0.03914 0.06500 0.01300 55197.201210 0.002179 0.21624 0.04160 0.83908 1 1.04842 0.08564 0.48834 0.03987 0.22671 0.03949 0.10487 0.01826 55197.264853 0.002934 0.15150 0.03395 0.64394 1 1.01804 0.08342 0.46827 0.03836 0.15424 0.03217 0.07073 0.01475 55197.269240 0.001453 0.28313 0.06297 0.87689 1 0.90498 0.09488 0.41988 0.04402 0.25622 0.05026 0.11860 0.02326 55197.334200 0.002978 0.11713 0.02595 0.94532 1 1.19828 0.08946 0.40579 0.03024 0.14036 0.02928 0.04747 0.00990 55197.631156 0.035597 0.20817 0.03985 0.07301 1 1.02655 0.08169 0.35722 0.02842 0.21370 0.03721 0.07377 0.01284 55197.669454 0.002702 0.19340 0.03632 0.98755 1 1.08747 0.08317 0.38279 0.02927 0.21032 0.03607 0.07404 0.01270 55197.730343 0.001453 0.19353 0.04738 1.00000 1 0.95099 0.09465 0.41224 0.04102 0.18404 0.04116 0.08000 0.01789 55197.733336 0.001540 0.20107 0.04947 0.99057 1 0.88008 0.09031 0.37999 0.03899 0.17695 0.03957 0.07619 0.01704 55197.736851 0.001975 0.21418 0.04263 0.98529 1 0.99918 0.08569 0.43174 0.03702 0.21400 0.03844 0.09254 0.01662
