/* ** ** 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 57241.581523 0.000541 0.11457 0.02704 0.96791 0 2.36545 0.17849 1.92665 0.14537 0.27101 0.06060 0.22136 0.04950 57241.582446 0.000382 0.16418 0.03958 0.95455 0 2.38428 0.21492 1.93650 0.17456 0.39144 0.08753 0.31799 0.07110 57241.583215 0.000388 0.15899 0.03744 0.96269 0 2.52356 0.22336 2.05035 0.18147 0.40121 0.08755 0.32612 0.07117 57241.584046 0.000443 0.12004 0.02852 1.00000 0 2.69748 0.21644 2.18175 0.17506 0.32380 0.07241 0.26187 0.05856 57241.585276 0.000787 0.07600 0.01766 0.98162 0 2.43010 0.15323 1.97498 0.12453 0.18468 0.04130 0.15006 0.03356 57241.586714 0.000651 0.08555 0.01994 0.98222 0 2.60759 0.17192 2.11947 0.13973 0.22307 0.04988 0.18130 0.04054 57241.587868 0.000503 0.09865 0.02348 0.97126 0 2.92296 0.20917 2.37185 0.16973 0.28835 0.06544 0.23399 0.05310 57241.588823 0.000451 0.12947 0.03079 0.97436 0 2.50718 0.20303 2.03543 0.16483 0.32461 0.07258 0.26360 0.05894 57241.589946 0.000671 0.08375 0.01980 0.97845 0 2.57072 0.16988 2.08267 0.13763 0.21531 0.04886 0.17420 0.03953 57241.590985 0.000367 0.17697 0.04310 0.97638 0 2.24968 0.21698 1.82696 0.17621 0.39812 0.08902 0.32312 0.07225 57241.591919 0.000567 0.10554 0.02427 0.96939 0 2.57768 0.18713 2.09754 0.15228 0.27205 0.05937 0.22142 0.04832 57241.592915 0.000428 0.12398 0.02948 0.97973 0 2.74549 0.22194 2.22882 0.18018 0.34040 0.07612 0.27632 0.06179 57241.593803 0.000460 0.12509 0.03011 0.97484 0 2.51128 0.20170 2.04020 0.16386 0.31413 0.07129 0.25512 0.05790 57241.594651 0.000388 0.14792 0.03549 0.97015 0 2.56394 0.22325 2.08513 0.18156 0.37925 0.08480 0.30821 0.06892 57241.595614 0.000576 0.10110 0.02374 0.97990 0 2.51604 0.18057 2.03836 0.14629 0.25437 0.05688 0.20547 0.04594 57241.597032 0.000842 0.09681 0.01903 0.96907 0 2.59376 0.15193 2.10460 0.12327 0.25110 0.04711 0.20416 0.03830
