/* ** ** 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 54416.589278 0.000334 0.21583 0.03334 1.00000 1 23.82330 1.55202 4.20419 0.27387 5.14172 0.72016 0.90541 0.12682 54416.590571 0.000959 0.27788 0.02258 0.98485 1 24.92253 0.94413 4.35834 0.16510 6.92545 0.49786 1.21227 0.08715 54416.592503 0.000973 0.27543 0.02229 1.00000 1 24.47361 0.92738 4.29117 0.16261 6.74077 0.48209 1.18169 0.08451 54416.594493 0.001017 0.25402 0.02035 1.00000 1 25.59411 0.92715 4.47996 0.16229 6.50146 0.46452 1.13818 0.08132 54416.595844 0.000334 0.25705 0.03988 0.95652 1 21.70897 1.51962 3.79760 0.26583 5.58021 0.77259 0.97610 0.13514 54416.596483 0.000305 0.22684 0.03656 1.00000 1 23.44719 1.65020 4.10364 0.28881 5.31872 0.77112 0.93092 0.13497 54416.606507 0.009720 0.25687 0.01633 0.16676 1 25.10847 0.72036 4.43010 0.12704 6.44972 0.36584 1.13608 0.06442
