/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 56414.547073 0.000315 0.47560 0.08149 0.97248 0 2.32533 0.22495 1.98562 0.19209 1.10593 0.15641 0.94497 0.13364 56414.547811 0.000422 0.31965 0.05267 0.96575 0 2.61233 0.21035 2.18985 0.17632 0.83502 0.12004 0.70013 0.10064 56414.548532 0.000298 0.47755 0.08227 0.98058 0 2.48642 0.24460 2.07862 0.20449 1.18739 0.16793 0.99175 0.14025 56414.549206 0.000376 0.53841 0.08586 0.96154 0 2.15798 0.20315 1.82762 0.17204 1.16188 0.14955 0.98207 0.12637 56414.550033 0.000451 0.30256 0.05008 0.98077 0 2.47583 0.19625 2.10521 0.16686 0.74909 0.10886 0.63891 0.09285 56414.550858 0.000373 0.43399 0.07481 0.97674 0 2.11107 0.19832 1.79667 0.16878 0.91617 0.13241 0.77965 0.11269 56414.551544 0.000312 0.40660 0.06864 0.98148 0 2.76968 0.25199 2.31620 0.21075 1.12615 0.16014 0.94042 0.13372 56414.552227 0.000370 0.38268 0.06539 0.99219 0 2.34572 0.21084 2.01222 0.18086 0.89767 0.13046 0.76971 0.11186 56414.552988 0.000391 0.38590 0.06466 0.97778 0 2.30587 0.20436 1.95470 0.17324 0.88983 0.12652 0.75518 0.10738 56414.553685 0.000307 0.45557 0.07748 1.00000 0 2.46456 0.23790 2.11605 0.20426 1.12277 0.15722 0.96387 0.13497 56414.554379 0.000388 0.36228 0.06033 0.97761 0 2.45443 0.21272 2.10119 0.18210 0.88918 0.12643 0.76095 0.10820 56414.555106 0.000339 0.46698 0.07989 0.99145 0 2.20330 0.21415 1.88096 0.18282 1.02891 0.14486 0.87662 0.12340 56414.555803 0.000359 0.37953 0.06348 0.98387 0 2.51155 0.22126 2.15294 0.18967 0.95321 0.13554 0.81708 0.11618 56414.556605 0.000443 0.28024 0.04588 0.98693 0 2.71189 0.20848 2.31891 0.17825 0.75998 0.10986 0.65057 0.09403 56414.557669 0.000622 0.37475 0.04855 0.98140 0 2.45032 0.16566 2.10402 0.14225 0.91826 0.10149 0.78839 0.08714
