/* ** ** 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 55674.160934 0.000295 0.09467 0.01440 1.00000 0 12.35129 0.55133 10.23126 0.45650 1.16930 0.16997 0.96404 0.14004 55674.161533 0.000304 0.09442 0.01398 0.98095 0 12.60120 0.55371 10.30256 0.45273 1.18985 0.16827 0.97249 0.13753 55674.162806 0.000969 0.11447 0.00883 0.98507 0 12.80073 0.31288 10.36871 0.25340 1.46535 0.10716 1.18634 0.08675 55674.164675 0.000900 0.12119 0.00932 0.98071 0 13.07097 0.32864 10.63834 0.26746 1.58402 0.11508 1.28960 0.09367 55674.166455 0.000880 0.12482 0.00979 0.97368 0 13.04598 0.33478 10.49569 0.26933 1.62845 0.12072 1.31021 0.09711 55674.168116 0.000781 0.13567 0.01049 0.98889 0 13.42891 0.35614 10.85649 0.28792 1.82196 0.13232 1.47314 0.10700 55674.169779 0.000883 0.12026 0.00919 0.99672 0 13.40544 0.33464 10.86801 0.27129 1.61215 0.11650 1.30702 0.09444 55674.171634 0.000972 0.11306 0.00844 0.97619 0 13.28921 0.31670 10.80768 0.25754 1.50244 0.10625 1.22155 0.08638 55674.173101 0.000495 0.09396 0.01124 0.97661 0 13.54753 0.45335 11.05690 0.36997 1.27286 0.14615 1.03872 0.11928
