/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 56586.864450 0.000422 0.19020 0.04490 0.97945 0 1.85433 0.17598 1.60091 0.15193 0.35270 0.07623 0.30450 0.06581 56586.865657 0.000784 0.09614 0.02252 0.95572 0 1.86372 0.13021 1.60901 0.11241 0.17919 0.04007 0.15470 0.03459 56586.866886 0.000446 0.14976 0.03602 0.97403 0 2.06595 0.18317 1.78360 0.15814 0.30940 0.06918 0.26711 0.05973 56586.867937 0.000605 0.12650 0.03052 0.96172 0 1.80108 0.14734 1.55493 0.12720 0.22784 0.05172 0.19670 0.04465 56586.869696 0.001155 0.14210 0.02466 0.97115 0 1.60140 0.09875 1.38254 0.08525 0.22756 0.03692 0.19646 0.03187 56586.978789 0.000391 0.16545 0.04056 0.97778 0 2.07428 0.19193 1.81021 0.16750 0.34319 0.07791 0.29950 0.06799 56586.979614 0.000434 0.16060 0.03874 0.96667 0 1.97148 0.17848 1.72050 0.15576 0.31663 0.07080 0.27632 0.06179 56586.980586 0.000538 0.13216 0.03189 0.95161 0 1.93664 0.15850 1.69009 0.13832 0.25594 0.05810 0.22336 0.05071 56586.981506 0.000382 0.20111 0.04997 0.96212 0 1.77364 0.17915 1.54785 0.15634 0.35670 0.08098 0.31129 0.07067 56586.982944 0.001056 0.10847 0.01996 0.95890 0 2.02375 0.11745 1.76612 0.10249 0.21951 0.03832 0.19156 0.03344
