/* ** ** 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 59996.119325 0.000755 0.10354 0.00777 0.98851 0 16.82074 0.39106 15.00144 0.34876 1.74167 0.12419 1.55431 0.11081 59996.120734 0.000654 0.11773 0.00907 0.98673 0 16.73892 0.41506 14.99322 0.37177 1.97073 0.14369 1.76465 0.12868 59996.122117 0.000729 0.10625 0.00819 0.97222 0 16.91052 0.39783 15.03669 0.35375 1.79680 0.13195 1.59872 0.11736 59996.123627 0.000781 0.09720 0.00730 0.98519 0 17.13712 0.38425 15.35422 0.34427 1.66574 0.11937 1.49250 0.10695 59996.124993 0.000584 0.12639 0.00963 1.00000 0 17.40433 0.44430 15.63521 0.39913 2.19970 0.15787 1.97615 0.14183 59996.126260 0.000683 0.10954 0.00848 1.00000 0 16.82823 0.40567 15.07542 0.36342 1.84343 0.13567 1.65120 0.12154 59996.127623 0.000680 0.10730 0.00817 0.99149 0 17.72425 0.41751 15.82400 0.37274 1.90186 0.13774 1.69677 0.12291 59996.128977 0.000674 0.11528 0.00873 0.99571 0 16.55831 0.40747 14.84811 0.36538 1.90877 0.13678 1.71123 0.12263 59996.130789 0.001137 0.11125 0.00662 0.99237 0 16.67666 0.31326 14.93548 0.28054 1.85533 0.10482 1.66183 0.09388
