/* ** ** 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 58127.494650 0.000460 0.24067 0.00868 1.00000 0 56.41415 0.89172 51.53758 0.81463 13.57700 0.44019 12.40260 0.40210 58127.495550 0.000440 0.26998 0.00970 1.00000 0 52.98850 0.88045 48.74846 0.80996 14.30604 0.45556 13.16241 0.41909 58127.496108 0.000119 0.18685 0.01500 1.00000 0 55.12146 1.75046 51.16996 1.62497 10.29956 0.75926 9.56120 0.70483 58127.496681 0.000454 0.24554 0.00886 1.00000 0 55.55053 0.88673 51.34277 0.81952 13.64004 0.44136 12.61164 0.40802 58127.497598 0.000463 0.24973 0.00912 1.00000 0 53.14102 0.86243 49.13544 0.79738 13.27106 0.43387 12.27097 0.40117 58127.498524 0.000463 0.25386 0.00919 1.00000 0 52.80120 0.86119 48.77017 0.79542 13.40404 0.43295 12.37930 0.39982 58127.499444 0.000457 0.25064 0.00905 0.99367 0 54.50257 0.87415 50.46273 0.80933 13.66040 0.44200 12.64570 0.40917 58127.500335 0.000434 0.26318 0.00957 1.00000 0 53.89077 0.89414 50.02176 0.82994 14.18283 0.45879 13.16452 0.42585 58127.501218 0.000448 0.25823 0.00928 1.00000 0 53.51785 0.87556 49.66811 0.81258 13.81994 0.44212 12.82584 0.41032 58127.502210 0.000544 0.24561 0.00823 0.99560 0 54.35551 0.80689 50.27500 0.74630 13.35003 0.40082 12.35185 0.37085
