/* ** ** Swift/XRT hardness ratio for 3C 454.3. ** 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 57027.127097 0.000336 0.47995 0.13307 0.97414 0 1.00523 0.16090 0.72668 0.11632 0.48246 0.10922 0.35048 0.07934 57027.127817 0.000385 0.50751 0.14151 0.96241 0 0.84600 0.13769 0.61206 0.09961 0.42935 0.09720 0.30941 0.07004 57027.128619 0.000417 0.55900 0.15630 0.96528 0 0.72160 0.12110 0.51552 0.08651 0.40338 0.09021 0.28825 0.06445 57027.129501 0.000466 0.54820 0.15408 0.95652 0 0.65149 0.10970 0.46991 0.07912 0.35714 0.08038 0.25867 0.05820 57027.130312 0.000344 0.60212 0.15986 0.97479 0 0.90579 0.14885 0.65966 0.10840 0.54540 0.11372 0.39721 0.08282 57027.131394 0.000738 0.57453 0.10407 0.96471 0 0.96145 0.10617 0.69185 0.07639 0.55238 0.07932 0.39716 0.05702 57027.132681 0.000550 0.37204 0.09830 0.93684 0 0.83268 0.11333 0.59768 0.08133 0.30979 0.07016 0.22249 0.05037 57027.133755 0.000524 0.74479 0.16793 0.97238 0 0.73807 0.10912 0.53134 0.07855 0.54971 0.09358 0.39576 0.06737 57027.134782 0.000503 0.70268 0.16153 0.95402 0 0.77874 0.11571 0.56425 0.08383 0.54720 0.09598 0.39547 0.06936 57027.135592 0.000307 0.51687 0.14247 0.95283 0 1.06514 0.17166 0.76898 0.12391 0.55054 0.12312 0.39670 0.08870 57027.136264 0.000365 0.45612 0.12679 0.96032 0 1.00132 0.15734 0.71644 0.11256 0.45672 0.10472 0.32348 0.07414 57027.136941 0.000312 0.50787 0.14046 0.97222 0 1.03092 0.16778 0.75144 0.12229 0.52357 0.11707 0.38159 0.08533 57027.138049 0.000796 0.38746 0.07953 0.93091 0 0.91663 0.09970 0.66497 0.07232 0.35516 0.06183 0.25824 0.04495
