/* ** ** 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 57065.713080 0.000399 0.39801 0.06717 0.99275 0 2.15297 0.19551 1.82734 0.16594 0.85690 0.12189 0.72738 0.10347 57065.713876 0.000396 0.42760 0.07210 0.97810 0 2.10213 0.19495 1.77914 0.16500 0.89886 0.12659 0.75862 0.10684 57065.714570 0.000298 0.44907 0.07811 1.00000 0 2.56520 0.25367 2.13196 0.21082 1.15196 0.16483 0.96248 0.13771 57065.715297 0.000428 0.36529 0.06181 0.99324 0 2.16927 0.18986 1.83003 0.16017 0.79241 0.11475 0.66738 0.09662 57065.716063 0.000339 0.46730 0.08109 0.97436 0 2.19618 0.21567 1.86099 0.18276 1.02627 0.14684 0.86961 0.12443 57065.716801 0.000399 0.37752 0.06420 0.99275 0 2.24996 0.20384 1.90675 0.17274 0.84939 0.12225 0.71986 0.10360 57065.717577 0.000376 0.36223 0.06076 0.99231 0 2.50781 0.21949 2.12283 0.18580 0.90840 0.12998 0.76849 0.10996 57065.718271 0.000318 0.44322 0.07711 1.00000 0 2.42859 0.24032 2.03699 0.20157 1.07640 0.15402 0.90123 0.12895 57065.718974 0.000385 0.36144 0.06008 0.98496 0 2.50628 0.21889 2.11152 0.18439 0.90587 0.12811 0.76463 0.10814 57065.719828 0.000469 0.35353 0.05850 0.97531 0 2.10949 0.17839 1.78653 0.15108 0.74577 0.10608 0.63070 0.08972 57065.720736 0.000440 0.39379 0.06692 0.96053 0 2.03980 0.18436 1.71438 0.15496 0.80326 0.11561 0.67548 0.09722 57065.721602 0.000425 0.32381 0.05339 0.96599 0 2.55299 0.20927 2.15514 0.17666 0.82668 0.11828 0.69814 0.09989 57065.722464 0.000437 0.30303 0.05008 0.99338 0 2.54734 0.20295 2.15841 0.17196 0.77192 0.11176 0.65403 0.09469 57065.723262 0.000362 0.46045 0.07985 0.97600 0 2.08262 0.20410 1.76483 0.17296 0.95894 0.13721 0.81259 0.11627 57065.724310 0.000686 0.26231 0.03822 0.98312 0 2.36628 0.15828 2.00030 0.13379 0.62070 0.08034 0.52423 0.06785
