/* ** ** 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 58244.186548 0.000448 0.33244 0.07151 0.94194 0 1.37881 0.14515 1.18660 0.12491 0.45837 0.08599 0.39434 0.07398 58244.187399 0.000402 0.44906 0.07747 0.99281 0 1.87535 0.18298 1.60709 0.15678 0.84215 0.11981 0.72205 0.10272 58244.188290 0.000489 0.41258 0.07004 0.94675 0 1.73025 0.15801 1.50153 0.13712 0.71387 0.10216 0.61950 0.08866 58244.189279 0.000501 0.36339 0.06080 0.97110 0 1.88357 0.16330 1.62552 0.14092 0.68447 0.09795 0.59000 0.08443 58244.190252 0.000472 0.47905 0.08125 0.98160 0 1.57266 0.15354 1.35885 0.13267 0.75338 0.10448 0.65108 0.09029 58244.191285 0.000561 0.32070 0.05251 0.96392 0 1.91871 0.15547 1.65955 0.13447 0.61533 0.08754 0.53285 0.07580 58244.192309 0.000463 0.43464 0.07522 0.95625 0 1.74283 0.16691 1.49738 0.14340 0.75751 0.10920 0.65067 0.09382 58244.193223 0.000451 0.49415 0.08717 0.96795 0 1.53431 0.15642 1.32487 0.13505 0.75818 0.10914 0.65296 0.09400 58244.194161 0.000486 0.43563 0.07485 0.98214 0 1.61120 0.15318 1.38446 0.13161 0.70188 0.10045 0.60073 0.08597 58244.195072 0.000420 0.26907 0.05765 0.97241 0 1.70327 0.17201 1.47875 0.14933 0.45830 0.08661 0.39783 0.07518 58244.196007 0.000515 0.41226 0.06905 0.94944 0 1.70526 0.15610 1.48016 0.13550 0.70302 0.09861 0.61022 0.08559 58244.197210 0.000689 0.40767 0.05836 0.98319 0 1.68112 0.12984 1.45894 0.11268 0.68535 0.08261 0.59481 0.07170
