/* ** ** 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 54695.839898 0.000816 0.10662 0.01313 0.98048 0 5.49757 0.21110 4.96354 0.19058 0.58613 0.06861 0.52891 0.06190 54695.841485 0.000755 0.11402 0.02752 1.00000 1 5.21592 0.39988 1.31644 0.10092 0.59473 0.13609 0.15053 0.03445 54695.842923 0.000683 0.13768 0.03137 1.00000 1 5.41333 0.43460 1.35772 0.10900 0.74532 0.15891 0.18723 0.03992 54695.844492 0.000886 0.09628 0.02272 0.95082 1 5.62009 0.39202 1.42655 0.09950 0.54110 0.12196 0.13694 0.03086 54695.846642 0.001264 0.13378 0.02441 0.95097 1 4.87428 0.30348 1.22799 0.07645 0.65208 0.11184 0.16438 0.02819 54696.041402 0.000489 0.08719 0.01802 0.93079 0 4.60362 0.26528 3.77132 0.21729 0.40140 0.07966 0.32773 0.06503 54696.042966 0.001060 0.12306 0.02936 0.95890 1 3.93445 0.30887 0.92237 0.07241 0.48417 0.10908 0.11347 0.02557 54696.046307 0.002280 0.09766 0.01762 0.96658 1 3.89377 0.20886 0.91320 0.04898 0.38026 0.06552 0.08924 0.01537 54696.510932 0.000327 0.10960 0.02337 0.98965 0 4.65415 0.31100 4.04232 0.27012 0.51011 0.10328 0.44302 0.08970 54696.512919 0.001641 0.08981 0.01713 0.98123 1 4.66927 0.25685 1.20477 0.06627 0.41933 0.07657 0.10823 0.01976 54696.578762 0.000113 0.04146 0.02118 0.97732 0 5.82923 0.61174 5.07374 0.53246 0.24166 0.12083 0.21024 0.10512 54696.579688 0.000770 0.13937 0.03352 1.00000 1 4.18163 0.35187 1.07696 0.09062 0.58279 0.13132 0.14985 0.03377 54696.582244 0.001758 0.07710 0.01548 0.98191 1 4.55758 0.24341 1.17383 0.06269 0.35138 0.06802 0.09041 0.01750 54696.645246 0.000622 0.09952 0.01501 0.96744 0 5.31257 0.23711 4.81810 0.21503 0.52871 0.07614 0.48052 0.06919 54696.646373 0.000505 0.08952 0.01603 0.97706 0 5.20069 0.26644 4.47334 0.22919 0.46559 0.07986 0.39974 0.06855 54696.647439 0.000561 0.12654 0.01922 0.97938 0 4.76080 0.24108 4.11971 0.20862 0.60246 0.08629 0.52134 0.07467 54696.648697 0.000697 0.11119 0.01557 0.97251 0 4.91433 0.21642 4.41250 0.19427 0.54643 0.07263 0.49102 0.06527 54696.817397 0.167988 0.12058 0.02498 0.00556 1 5.17382 0.34468 1.34097 0.08933 0.62386 0.12235 0.16179 0.03173 54696.982523 0.000295 0.07254 0.01796 0.99020 0 5.69959 0.35764 5.18838 0.32557 0.41345 0.09901 0.37553 0.08996 54696.983712 0.000894 0.08453 0.01056 0.98058 0 6.12546 0.21145 5.56577 0.19212 0.51776 0.06217 0.46898 0.05632
