/* ** ** 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 55560.161078 0.000402 0.07797 0.01158 0.97122 0 10.46728 0.41254 9.41776 0.37119 0.81612 0.11688 0.73449 0.10520 55560.161816 0.000336 0.09714 0.01442 0.98276 0 10.06877 0.44306 9.12750 0.40163 0.97807 0.13871 0.88737 0.12581 55560.162479 0.000327 0.09814 0.01483 0.98230 0 10.56575 0.46069 9.56859 0.41721 1.03693 0.15002 0.93804 0.13569 55560.163124 0.000318 0.10280 0.01582 0.95455 0 9.95525 0.45538 9.01368 0.41234 1.02341 0.15035 0.92511 0.13594 55560.163827 0.000385 0.08031 0.01197 0.95489 0 10.83751 0.43205 9.82332 0.39161 0.87035 0.12499 0.78858 0.11321 55560.164530 0.000318 0.09559 0.01390 0.97273 0 11.48528 0.48973 10.27304 0.43805 1.09784 0.15261 0.98286 0.13663 55560.165190 0.000341 0.08750 0.01323 0.99153 0 10.57942 0.45182 9.57896 0.40909 0.92568 0.13427 0.83886 0.12169 55560.165852 0.000321 0.09029 0.01383 0.98198 0 10.84830 0.46924 9.87020 0.42693 0.97953 0.14393 0.89116 0.13095 55560.166492 0.000318 0.10093 0.01459 0.99091 0 10.84436 0.47610 9.76722 0.42880 1.09452 0.15075 0.98321 0.13538 55560.167163 0.000353 0.08862 0.01339 0.95902 0 10.49171 0.44273 9.46111 0.39918 0.92974 0.13490 0.83886 0.12169 55560.167892 0.000376 0.07595 0.01170 0.96923 0 11.10649 0.44135 10.05424 0.39952 0.84351 0.12559 0.76290 0.11356 55560.168839 0.000570 0.10424 0.01147 0.96500 0 10.56176 0.35115 9.55288 0.31759 1.10093 0.11552 0.99562 0.10447
