/* ** ** 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 55125.678073 0.000477 0.49451 0.08659 0.98788 0 1.44963 0.14795 1.23858 0.12638 0.71686 0.10199 0.61128 0.08697 55125.678970 0.000420 0.60376 0.10910 0.96552 0 1.38041 0.15227 1.17393 0.12946 0.83343 0.11929 0.70795 0.10132 55125.679736 0.000347 0.64316 0.11920 0.98333 0 1.49654 0.17302 1.29230 0.14941 0.96251 0.13943 0.83101 0.12038 55125.680486 0.000402 0.61723 0.11162 0.96403 0 1.40323 0.15814 1.21139 0.13651 0.86612 0.12249 0.74751 0.10571 55125.681261 0.000373 0.71948 0.13578 0.99225 0 1.24947 0.15238 1.07597 0.13123 0.89897 0.12947 0.77020 0.11090 55125.682494 0.000859 0.37996 0.05172 0.97942 0 1.59081 0.11431 1.36778 0.09828 0.60444 0.06988 0.51978 0.06009
