/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 54946.668547 0.001278 0.33002 0.08508 0.97727 1 0.35350 0.04534 0.28326 0.03633 0.11666 0.02609 0.09302 0.02080 54946.670725 0.000901 0.71558 0.21113 0.98387 1 0.23089 0.04444 0.18305 0.03523 0.16522 0.03695 0.13115 0.02933 54946.672527 0.000901 0.77409 0.23224 1.00000 1 0.20971 0.04195 0.16667 0.03333 0.16234 0.03630 0.12903 0.02885 54946.674415 0.000988 0.46143 0.12520 0.98529 1 0.32499 0.04993 0.25878 0.03976 0.14996 0.03353 0.11940 0.02670 54946.676376 0.000973 0.47503 0.12974 0.98507 1 0.31989 0.04961 0.25333 0.03929 0.15196 0.03416 0.12060 0.02711 54946.678613 0.001235 0.81556 0.18641 0.97099 1 0.25943 0.03976 0.20743 0.03179 0.21158 0.03588 0.16914 0.02868 54946.873319 0.000784 0.57523 0.16125 0.98148 1 0.32814 0.05547 0.26415 0.04465 0.18876 0.04221 0.15094 0.03375 54946.874946 0.000842 0.75581 0.22590 0.98276 1 0.23150 0.04559 0.18499 0.03643 0.17497 0.03934 0.13964 0.03139 54946.877125 0.001336 0.31710 0.08158 0.98913 1 0.35179 0.04476 0.27820 0.03539 0.11155 0.02494 0.08791 0.01966 54946.879391 0.000930 0.58004 0.16346 0.96875 1 0.28128 0.04824 0.22295 0.03824 0.16315 0.03648 0.12903 0.02885 54946.881352 0.001031 0.51359 0.13599 1.00000 1 0.30252 0.04750 0.23999 0.03768 0.15537 0.03313 0.12394 0.02643 54946.883763 0.001380 0.35048 0.09109 0.97895 1 0.31081 0.04117 0.24516 0.03247 0.10893 0.02436 0.08602 0.01924
