/* ** ** 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 58195.369414 0.000483 0.46221 0.08063 0.98802 0 2.17597 0.21545 1.31223 0.12956 1.00576 0.14446 0.60070 0.08597 58195.370502 0.000605 0.47013 0.08220 0.98086 0 1.90012 0.19082 1.02546 0.10298 0.89330 0.12786 0.48349 0.06920 58195.371526 0.000414 0.31903 0.07256 0.95105 0 2.24179 0.25561 1.21992 0.13910 0.71520 0.14075 0.38999 0.07674 58195.372235 0.000295 0.33762 0.08909 0.99020 0 2.14781 0.28902 1.16096 0.15621 0.72514 0.16461 0.39149 0.08886 58195.373123 0.000593 0.34256 0.05725 0.97073 0 2.70034 0.23300 1.45110 0.12522 0.92503 0.13240 0.49807 0.07128 58195.374234 0.000518 0.33168 0.06713 0.92737 0 2.22343 0.22339 1.19356 0.11992 0.73748 0.12957 0.39509 0.06940 58195.375056 0.000304 0.30679 0.07935 0.96190 0 2.37089 0.29408 1.27663 0.15835 0.72737 0.16508 0.39149 0.08886 58195.375944 0.000584 0.37335 0.07261 0.94554 0 1.96289 0.19854 1.04462 0.10566 0.73284 0.12173 0.39031 0.06483 58195.376948 0.000420 0.72150 0.13630 0.97931 0 1.79850 0.22171 0.96501 0.11895 1.29763 0.18576 0.69799 0.09990 58195.377944 0.000576 0.46167 0.07799 0.97990 0 2.17082 0.20943 1.15377 0.11129 1.00219 0.13899 0.53422 0.07408 58195.379064 0.000544 0.48714 0.08606 0.97872 0 2.07559 0.21223 1.09781 0.11219 1.01110 0.14566 0.53581 0.07715 58195.380079 0.000472 0.33896 0.07516 0.95092 0 1.98444 0.22352 1.05441 0.11877 0.67264 0.12847 0.35850 0.06848
