/* ** ** 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 53454.097914 0.000012 0.18199 0.09964 0.98651 0 11.87909 2.64994 11.14901 2.48708 2.16183 1.08091 2.02896 1.01448 53454.163192 0.000012 0.05530 0.04053 0.98651 0 19.98145 3.84543 18.34426 3.53036 1.10502 0.78137 1.01448 0.71735 53454.233331 0.000012 0.17567 0.09762 0.98651 0 12.58547 3.05242 11.55009 2.80131 2.21084 1.10542 2.02896 1.01448 53454.300703 0.000012 0.25913 0.10743 0.98651 0 16.69013 3.61364 15.65990 3.39058 4.32488 1.52908 4.05792 1.43469 53454.434037 0.000012 0.15442 0.06926 0.98562 0 21.07063 3.91272 19.72693 3.66320 3.25368 1.32831 3.04619 1.24360 53454.498620 0.000012 0.30732 0.13801 0.98562 0 12.71521 3.08389 11.56406 2.80470 3.90766 1.47696 3.55389 1.34324 53454.704870 0.000012 0.21952 0.11168 0.98562 0 12.34762 2.99474 11.56406 2.80470 2.71049 1.21217 2.53849 1.13525 53454.845831 0.000012 0.01347 0.03202 0.98384 0 19.73611 4.65185 18.01432 4.24602 0.26594 0.62877 0.24274 0.57392
