/* ** ** 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 58526.435481 0.000414 0.35228 0.05923 0.96503 0 2.34486 0.20372 2.02750 0.17613 0.82605 0.11890 0.71455 0.10286 58526.436329 0.000434 0.41674 0.07146 0.98000 0 1.85871 0.17566 1.61893 0.15300 0.77459 0.11084 0.67434 0.09650 58526.437200 0.000437 0.37841 0.06334 0.98013 0 2.05970 0.18438 1.78851 0.16010 0.77942 0.11023 0.67680 0.09571 58526.437952 0.000315 0.54209 0.09823 0.97248 0 1.95879 0.21340 1.70728 0.18600 1.06184 0.15376 0.92536 0.13400 58526.438632 0.000365 0.46512 0.08127 0.97619 0 2.00297 0.20325 1.74234 0.17680 0.93162 0.13253 0.81014 0.11525 58526.439393 0.000396 0.40866 0.06892 0.98540 0 2.08860 0.19193 1.81586 0.16687 0.85352 0.12071 0.74198 0.10493 58526.440220 0.000431 0.40363 0.06803 0.96644 0 1.97241 0.17830 1.71416 0.15496 0.79611 0.11325 0.69199 0.09844 58526.441094 0.000443 0.31123 0.05049 0.96078 0 2.54385 0.20115 2.21027 0.17478 0.79171 0.11215 0.68797 0.09745 58526.441962 0.000425 0.38699 0.06579 0.97959 0 2.03520 0.18409 1.76923 0.16003 0.78760 0.11337 0.68478 0.09857 58526.442830 0.000443 0.29807 0.04869 0.98039 0 2.55129 0.20102 2.21734 0.17470 0.76046 0.10882 0.66085 0.09457 58526.443617 0.000344 0.44704 0.07826 0.96639 0 2.17661 0.21131 1.89777 0.18424 0.97302 0.14175 0.84842 0.12359 58526.444375 0.000414 0.37921 0.06368 0.96503 0 2.17911 0.19148 1.89443 0.16646 0.82633 0.11824 0.71832 0.10279 58526.445304 0.000515 0.40924 0.05964 0.98876 0 2.14616 0.17055 1.86351 0.14809 0.87830 0.10730 0.76263 0.09317
