/* ** ** 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 57628.078593 0.000567 0.16540 0.04054 0.97449 0 1.62211 0.15004 1.25016 0.11560 0.26830 0.06089 0.20706 0.04698 57628.079611 0.000451 0.18583 0.04537 0.98077 0 1.84176 0.18051 1.40244 0.13745 0.34225 0.07654 0.26187 0.05856 57628.080517 0.000454 0.17383 0.04393 0.94904 0 1.93525 0.18588 1.48157 0.14231 0.33640 0.07863 0.25848 0.06043 57628.081634 0.000663 0.13035 0.03150 0.97817 0 1.77408 0.14738 1.35263 0.11235 0.23126 0.05247 0.17656 0.04006 57628.082837 0.000541 0.16483 0.04096 0.94118 0 1.74816 0.16325 1.34494 0.12559 0.28816 0.06636 0.22177 0.05107 57628.084397 0.001019 0.14726 0.02640 0.96235 0 1.91107 0.12461 1.46510 0.09553 0.28143 0.04701 0.21576 0.03604
