/* ** ** 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 58248.669710 0.000657 0.11057 0.02611 0.98678 0 1.87499 0.14237 1.61953 0.12297 0.20732 0.04636 0.17887 0.04000 58248.671050 0.000683 0.10823 0.02549 0.97458 0 1.86080 0.13762 1.61065 0.11913 0.20139 0.04503 0.17420 0.03895 58248.672476 0.000744 0.09658 0.02295 0.95331 0 1.93437 0.13643 1.66173 0.11719 0.18682 0.04240 0.16139 0.03663 58248.673668 0.000448 0.17425 0.04236 0.97419 0 1.77414 0.16905 1.52438 0.14524 0.30914 0.06913 0.26534 0.05933 58248.675005 0.000888 0.08551 0.01995 0.97720 0 1.82498 0.12138 1.56180 0.10388 0.15606 0.03490 0.13356 0.02986 58248.676420 0.000527 0.12234 0.02903 0.96154 0 2.21267 0.17560 1.88046 0.14921 0.27069 0.06053 0.22895 0.05120 58248.677647 0.000700 0.09801 0.02333 0.97934 0 1.99618 0.14359 1.69895 0.12220 0.19565 0.04440 0.16684 0.03787 58248.679105 0.000758 0.13522 0.02635 0.95802 0 2.06681 0.14051 1.77476 0.12065 0.27948 0.05103 0.23944 0.04372
