/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 60021.021088 0.000518 0.13253 0.01011 1.00000 0 18.63283 0.48954 16.72531 0.43939 2.46933 0.17694 2.21799 0.15893 60021.022173 0.000567 0.11753 0.00919 1.00000 0 18.90298 0.47678 16.85555 0.42508 2.22165 0.16451 1.97910 0.14663 60021.023238 0.000498 0.13639 0.01048 1.00000 0 19.18961 0.51625 16.97083 0.45647 2.61726 0.18831 2.30930 0.16615 60021.024268 0.000532 0.12555 0.00961 0.98370 0 19.76467 0.50486 17.38371 0.44405 2.48146 0.17900 2.18340 0.15750 60021.025602 0.000802 0.11074 0.00738 0.98807 0 19.24304 0.40687 16.87695 0.35682 2.13098 0.13474 1.86846 0.11813 60021.090153 0.001007 0.12678 0.00976 0.98276 0 14.09447 0.36707 9.24670 0.23889 1.78696 0.12945 1.16055 0.08350 60021.092240 0.001079 0.12944 0.01010 0.97051 0 13.61119 0.35520 8.28951 0.21632 1.76190 0.12961 1.07242 0.07889 60021.094210 0.000891 0.11915 0.01037 0.98701 0 13.93822 0.39354 8.49861 0.23993 1.66077 0.13666 1.01390 0.08339
