/* ** ** 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 58165.416055 0.000807 0.30067 0.04878 0.79929 0 1.73055 0.13759 1.49146 0.11856 0.52032 0.07359 0.44917 0.06352 58165.417305 0.000443 0.42429 0.07256 0.99346 0 1.78583 0.16931 1.54461 0.14644 0.75771 0.10784 0.65535 0.09327 58165.418268 0.000521 0.42067 0.07195 0.96667 0 1.57007 0.14681 1.35294 0.12648 0.66049 0.09460 0.56930 0.08154 58165.419177 0.000388 0.48022 0.08297 0.95522 0 1.88671 0.18478 1.62622 0.15926 0.90604 0.12895 0.77822 0.11075 58165.420196 0.000631 0.38808 0.06469 0.74774 0 1.88716 0.16806 1.60221 0.14267 0.73237 0.10321 0.62338 0.08783 58165.421440 0.000613 0.27541 0.04459 0.97642 0 2.04674 0.15450 1.73894 0.13125 0.56370 0.08074 0.47854 0.06854 58165.422542 0.000489 0.38711 0.06531 0.95858 0 1.83197 0.16330 1.57814 0.14066 0.70918 0.10159 0.61147 0.08758 58165.423477 0.000446 0.41043 0.06930 0.98052 0 1.91016 0.17520 1.63267 0.14974 0.78398 0.11115 0.66928 0.09489 58165.424391 0.000469 0.37865 0.06428 1.00000 0 1.87999 0.17133 1.61720 0.14738 0.71185 0.10195 0.61147 0.08758 58165.425227 0.000367 0.47255 0.08254 0.98425 0 1.94678 0.19206 1.67128 0.16488 0.91995 0.13260 0.78803 0.11359 58165.426078 0.000483 0.36542 0.06071 0.97006 0 1.99161 0.17535 1.71437 0.15093 0.72776 0.10254 0.62726 0.08838 58165.427007 0.000446 0.38047 0.06468 0.99351 0 1.95647 0.17632 1.69221 0.15251 0.74438 0.10729 0.64382 0.09280 58165.427941 0.000489 0.41254 0.06867 0.99408 0 1.74584 0.16069 1.50296 0.13834 0.72024 0.09988 0.62008 0.08599
