/* ** ** 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 58169.400481 0.000483 0.38572 0.06644 0.97006 0 1.81832 0.16447 1.54882 0.14010 0.70136 0.10282 0.59896 0.08780 58169.401511 0.000547 0.36728 0.06224 0.97354 0 1.68950 0.14857 1.45201 0.12768 0.62052 0.08988 0.53302 0.07720 58169.402521 0.000463 0.37946 0.06339 0.96875 0 1.97634 0.17573 1.70396 0.15151 0.74995 0.10606 0.64624 0.09139 58169.403296 0.000312 0.28960 0.07394 0.99074 0 1.50162 0.18508 1.29299 0.15937 0.43487 0.09724 0.37446 0.08373 58169.404176 0.000561 0.42584 0.07184 0.94845 0 1.49060 0.13710 1.27718 0.11746 0.63476 0.08977 0.54438 0.07699 58169.405162 0.000425 0.46465 0.08153 0.97959 0 1.71438 0.16984 1.46968 0.14558 0.79659 0.11537 0.68108 0.09864 58169.406164 0.000576 0.38279 0.06310 0.95980 0 1.62270 0.14111 1.39727 0.12151 0.62115 0.08698 0.53492 0.07490 58169.407321 0.000582 0.32512 0.05348 0.97015 0 1.81735 0.14738 1.56296 0.12674 0.59086 0.08456 0.50832 0.07274 58169.408447 0.000544 0.37693 0.06321 0.96809 0 1.69697 0.15064 1.45381 0.12905 0.63964 0.09100 0.54750 0.07789 58169.409503 0.000512 0.46222 0.08029 0.97740 0 1.43872 0.14162 1.23917 0.12198 0.66501 0.09517 0.57296 0.08199 58169.410556 0.000541 0.37563 0.06311 0.98396 0 1.68483 0.15059 1.44500 0.12915 0.63288 0.09004 0.54154 0.07704
