/* ** ** 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 55118.696934 0.001024 0.19311 0.01497 0.99435 0 6.52338 0.20360 5.87973 0.18349 1.25971 0.08938 1.13522 0.08054 55118.698260 0.000301 0.17150 0.02624 0.97115 0 6.38913 0.37308 5.78296 0.33768 1.09570 0.15496 0.99175 0.14025 55118.698882 0.000321 0.18667 0.02827 0.96396 0 5.84243 0.34958 5.25554 0.31448 1.09063 0.15174 0.98230 0.13667 55118.699533 0.000330 0.19713 0.02940 0.97368 0 5.54273 0.33287 4.98754 0.29952 1.09266 0.14916 0.98299 0.13420 55118.700163 0.000301 0.20337 0.03133 0.99038 0 5.39559 0.34636 4.87517 0.31293 1.09732 0.15366 0.99194 0.13890 55118.700872 0.000408 0.19008 0.02563 0.97163 0 5.71709 0.30697 5.14172 0.27604 1.08668 0.13444 0.97872 0.12109 55118.702365 0.001085 0.20136 0.01575 0.97867 0 5.99392 0.19069 5.38270 0.17123 1.20691 0.08622 1.08298 0.07736 55118.703754 0.000304 0.17900 0.02750 0.98095 0 6.04747 0.36279 5.44738 0.32674 1.08249 0.15310 0.97249 0.13753 55118.704371 0.000312 0.16536 0.02558 0.97222 0 6.37017 0.37000 5.71267 0.33184 1.05337 0.15104 0.94377 0.13530 55118.705016 0.000333 0.15877 0.02449 0.97391 0 6.18154 0.35190 5.56459 0.31674 0.98145 0.14071 0.88478 0.12684 55118.705652 0.000304 0.17575 0.02700 0.98095 0 6.23360 0.37408 5.54865 0.33293 1.09554 0.15494 0.97249 0.13753 55118.706263 0.000307 0.15654 0.02539 0.98113 0 6.53601 0.37843 5.81392 0.33662 1.02312 0.15501 0.91165 0.13814 55118.706963 0.000394 0.18510 0.02600 0.96332 0 5.77612 0.31641 5.19482 0.28455 1.06914 0.13828 0.96123 0.12436 55118.708396 0.001039 0.19203 0.01604 0.97772 0 5.75808 0.19347 5.15025 0.17304 1.10572 0.08457 0.98966 0.07569 55118.709793 0.000359 0.16010 0.02443 0.99194 0 5.70755 0.32703 5.09227 0.29175 0.91377 0.12923 0.81436 0.11517 55118.710508 0.000356 0.15460 0.02383 0.99187 0 5.90270 0.33383 5.26538 0.29778 0.91257 0.13085 0.81226 0.11644 55118.711335 0.000472 0.18814 0.02361 0.96933 0 5.86241 0.28826 5.21428 0.25639 1.10296 0.12733 0.98133 0.11331
