/* ** ** 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 57184.982247 0.000573 0.11303 0.02707 0.98485 0 2.20289 0.16859 1.79330 0.13723 0.24898 0.05650 0.20280 0.04602 57184.983361 0.000541 0.11883 0.02815 0.97326 0 2.25492 0.17644 1.85695 0.14530 0.26796 0.05992 0.22015 0.04923 57184.984599 0.000697 0.08983 0.02130 0.96266 0 2.30125 0.15778 1.89743 0.13009 0.20673 0.04691 0.17046 0.03868 57184.985687 0.000391 0.15350 0.03698 0.98519 0 2.38257 0.21353 1.96359 0.17598 0.36572 0.08178 0.30125 0.06736 57184.986480 0.000402 0.15142 0.03639 0.98561 0 2.34398 0.20643 1.93234 0.17018 0.35493 0.07937 0.29246 0.06540 57184.987345 0.000463 0.12499 0.02964 0.97500 0 2.49938 0.19764 2.05634 0.16261 0.31240 0.06985 0.25684 0.05743 57184.988361 0.000553 0.11564 0.02772 0.96859 0 2.24848 0.17360 1.84806 0.14268 0.26002 0.05901 0.21376 0.04851 57184.989330 0.000417 0.15018 0.03610 0.98611 0 2.28584 0.20165 1.87997 0.16584 0.34328 0.07676 0.28216 0.06309 57184.990213 0.000466 0.12370 0.02935 0.96894 0 2.52830 0.20046 2.07701 0.16468 0.31276 0.06993 0.25684 0.05743 57184.991043 0.000365 0.15782 0.03805 0.98413 0 2.48659 0.22413 2.04768 0.18457 0.39244 0.08775 0.32312 0.07225 57184.992229 0.000822 0.07427 0.01643 0.98592 0 2.58243 0.15262 2.12016 0.12530 0.19179 0.04089 0.15740 0.03356
