/* ** ** 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 53561.585332 0.001013 0.40194 0.03424 0.98286 0 3.36258 0.15265 2.85053 0.12940 1.35154 0.09741 1.14519 0.08254 53561.586663 0.000318 0.31855 0.05212 0.98182 0 3.40827 0.27545 2.89659 0.23410 1.08569 0.15444 0.92268 0.13125 53561.587983 0.001001 0.44556 0.03797 0.97688 0 3.13031 0.14822 2.66382 0.12613 1.39475 0.09881 1.18674 0.08407 53561.590020 0.001036 0.41549 0.03531 0.96927 0 3.23338 0.14881 2.75418 0.12675 1.34344 0.09597 1.14423 0.08174 53561.592173 0.001117 0.41306 0.03474 0.96114 0 3.07525 0.13983 2.62111 0.11918 1.27027 0.08986 1.08258 0.07658 53561.594331 0.001042 0.43281 0.03703 0.98611 0 3.03437 0.14290 2.58439 0.12171 1.31330 0.09382 1.11844 0.07990 53561.595694 0.000321 0.38224 0.06531 0.99099 0 2.74306 0.24882 2.33315 0.21164 1.04850 0.15181 0.89180 0.12912 53561.596334 0.000318 0.31417 0.05145 0.96364 0 3.49370 0.27823 2.97631 0.23702 1.09761 0.15705 0.93521 0.13382 53561.597670 0.001019 0.45450 0.03944 0.98295 0 2.94609 0.14290 2.50873 0.12169 1.33900 0.09636 1.14006 0.08205 53561.599114 0.000425 0.36117 0.05061 0.97279 0 3.20092 0.23069 2.72413 0.19633 1.15609 0.13891 0.98381 0.11821 53561.600630 0.001091 0.45556 0.03960 0.95225 0 2.81947 0.13615 2.40275 0.11602 1.28445 0.09285 1.09446 0.07911 53561.602693 0.000972 0.43782 0.03756 0.96131 0 3.29145 0.15578 2.80486 0.13275 1.44108 0.10310 1.22765 0.08783 53561.604644 0.000978 0.44421 0.03823 0.96450 0 3.23130 0.15393 2.74168 0.13060 1.43536 0.10288 1.21774 0.08728 53561.605920 0.000298 0.34033 0.05615 0.98058 0 3.41108 0.28515 2.89901 0.24234 1.16089 0.16514 0.98663 0.14035 53561.607884 0.001667 0.40456 0.02848 0.94657 0 3.06938 0.11476 2.60626 0.09744 1.24175 0.07407 1.05489 0.06292
