/* ** ** 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 55684.265390 0.001031 0.42870 0.11488 0.98592 1 0.32323 0.04715 0.26479 0.03862 0.13857 0.03115 0.11371 0.02556 55684.267104 0.000683 0.72632 0.21312 1.00000 1 0.30256 0.05934 0.24762 0.04856 0.21976 0.04796 0.17873 0.03900 55684.268644 0.000857 0.75736 0.22527 1.00000 1 0.21694 0.04255 0.17931 0.03517 0.16430 0.03674 0.13559 0.03032 55684.270779 0.001278 0.33225 0.08624 0.97727 1 0.34058 0.04488 0.28195 0.03716 0.11316 0.02530 0.09302 0.02080 55684.272841 0.000784 0.48365 0.13281 0.98148 1 0.37638 0.05998 0.31136 0.04962 0.18203 0.04071 0.15095 0.03375 55684.274686 0.001060 0.40136 0.10798 1.00000 1 0.32688 0.04831 0.27000 0.03990 0.13119 0.02949 0.10904 0.02451 55684.276502 0.000755 0.70278 0.20608 0.98077 1 0.26817 0.05087 0.22320 0.04234 0.18846 0.04214 0.15686 0.03508 55684.278608 0.001351 0.36224 0.09273 0.98925 1 0.30144 0.03980 0.25087 0.03312 0.10920 0.02395 0.09087 0.01993 55684.280685 0.000726 0.65333 0.18860 1.00000 1 0.29429 0.05373 0.24490 0.04471 0.19227 0.04299 0.16000 0.03578 55684.282283 0.000872 0.45583 0.12382 0.98333 1 0.35741 0.05451 0.29656 0.04522 0.16292 0.03662 0.13491 0.03033 55684.283852 0.000697 0.76056 0.22130 0.97917 1 0.28321 0.05451 0.23479 0.04518 0.21540 0.04700 0.17873 0.03900 55684.286016 0.001467 0.35629 0.07946 0.93212 1 0.38793 0.04371 0.32157 0.03623 0.13822 0.02660 0.11472 0.02208 55684.400945 0.001278 0.34831 0.08929 0.98864 1 0.36069 0.04781 0.27470 0.03639 0.12563 0.02757 0.09609 0.02107 55684.403240 0.001017 0.40624 0.10893 1.00000 1 0.35875 0.05245 0.28000 0.04093 0.14574 0.03276 0.11371 0.02556 55684.405825 0.001569 0.25561 0.06394 0.96296 1 0.38587 0.04326 0.30113 0.03376 0.09863 0.02205 0.07692 0.01720 55684.408890 0.001496 0.52205 0.11820 0.99994 1 0.28512 0.03817 0.22360 0.02994 0.14884 0.02718 0.11651 0.02127
