/* ** ** 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 56819.534879 0.000538 0.11509 0.02756 0.95161 0 2.26174 0.17189 1.93546 0.14710 0.26030 0.05912 0.22330 0.05071 56819.536053 0.000637 0.11316 0.02667 0.96818 0 1.93180 0.14402 1.66164 0.12387 0.21860 0.04888 0.18811 0.04206 56819.537254 0.000564 0.11688 0.02763 0.97949 0 2.06998 0.15889 1.79575 0.13784 0.24194 0.05410 0.20977 0.04691 56819.538339 0.000521 0.13015 0.03139 0.97778 0 1.99943 0.16274 1.72769 0.14062 0.26022 0.05909 0.22457 0.05100 56819.539335 0.000475 0.16759 0.04063 0.99390 0 1.70205 0.15932 1.47206 0.13778 0.28524 0.06378 0.24581 0.05496 56819.540512 0.000703 0.08450 0.01970 0.98354 0 2.29762 0.15119 1.98327 0.13051 0.19414 0.04341 0.16764 0.03749 56819.541872 0.000657 0.10562 0.02488 0.98238 0 1.96639 0.14587 1.69965 0.12608 0.20768 0.04644 0.17967 0.04018 56819.543151 0.000622 0.11024 0.02639 0.97674 0 1.96777 0.14903 1.70695 0.12928 0.21693 0.04926 0.18821 0.04274 56819.544783 0.001010 0.12911 0.02229 0.97708 0 1.99422 0.11786 1.72920 0.10220 0.25747 0.04177 0.22325 0.03622
