/* ** ** 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 54826.221558 0.000959 0.71220 0.20702 0.96970 1 0.21614 0.04014 0.17576 0.03264 0.15393 0.03442 0.12500 0.02795 54826.223795 0.001278 0.60710 0.17205 0.95455 1 0.19506 0.03396 0.15714 0.02736 0.11842 0.02648 0.09524 0.02130 54826.226293 0.001220 0.59272 0.16840 0.98810 1 0.20107 0.03524 0.16195 0.02838 0.11918 0.02665 0.09639 0.02155 54826.228821 0.001307 0.51947 0.14301 0.96667 1 0.21548 0.03460 0.17681 0.02839 0.11193 0.02503 0.09196 0.02056 54826.231392 0.001264 0.55314 0.15353 0.96552 1 0.21040 0.03459 0.17210 0.02829 0.11638 0.02602 0.09524 0.02130 54826.233164 0.000508 1.25293 0.42797 1.00000 1 0.22176 0.05726 0.18182 0.04695 0.27785 0.06213 0.22857 0.05111 54826.234253 0.000581 0.96986 0.31072 1.00000 1 0.25063 0.05750 0.20541 0.04712 0.24308 0.05436 0.20000 0.04472 54826.236505 0.001670 0.50976 0.10486 0.99778 1 0.29909 0.03606 0.24606 0.02967 0.15246 0.02541 0.12550 0.02092
