/* ** ** 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 55755.388491 0.000857 0.81369 0.24504 1.00000 1 0.20484 0.04132 0.16813 0.03391 0.16667 0.03727 0.13559 0.03032 55755.390466 0.001118 0.45816 0.12401 0.96104 1 0.28450 0.04289 0.23467 0.03538 0.13035 0.02930 0.10757 0.02418 55755.393241 0.001656 0.29454 0.07533 1.00000 1 0.29006 0.03599 0.23818 0.02955 0.08544 0.01910 0.07018 0.01569 55755.396727 0.001830 0.26221 0.06426 0.98413 1 0.31319 0.03494 0.25824 0.02881 0.08212 0.01792 0.06774 0.01478 55755.399777 0.001220 0.42626 0.11389 0.97619 1 0.27851 0.04072 0.22878 0.03345 0.11872 0.02655 0.09756 0.02182 55755.402203 0.001206 0.53622 0.14934 0.96386 1 0.22492 0.03698 0.18500 0.03041 0.12061 0.02711 0.09950 0.02237 55755.404832 0.001423 0.40268 0.10231 0.97256 1 0.27813 0.03843 0.22836 0.03156 0.11200 0.02388 0.09233 0.01968 55755.522710 0.001743 0.36679 0.09607 0.97500 1 0.22769 0.03105 0.18586 0.02534 0.08351 0.01868 0.06838 0.01529 55755.526109 0.001656 0.53208 0.11887 0.95678 1 0.26045 0.03439 0.21175 0.02796 0.13858 0.02498 0.11332 0.02042
