/* ** ** Swift/XRT hardness ratio for 1ES 0647+250. ** 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 55506.213098 0.001714 0.27773 0.07008 0.97458 1 0.57650 0.06738 0.25174 0.02942 0.16011 0.03581 0.06957 0.01556 55506.216366 0.001554 0.30528 0.07866 0.99065 1 0.56774 0.07112 0.24569 0.03077 0.17332 0.03903 0.07501 0.01688 55506.219286 0.001365 0.32330 0.08291 0.94681 1 0.64461 0.08091 0.27720 0.03479 0.20840 0.04660 0.08989 0.02010 55506.222481 0.001830 0.29249 0.06944 0.98827 1 0.58974 0.06690 0.25219 0.02860 0.17249 0.03597 0.07388 0.01541 55506.269333 0.001758 0.24108 0.05994 0.95041 1 0.71884 0.07805 0.28744 0.03118 0.17330 0.03876 0.06957 0.01556 55506.273734 0.002644 0.21233 0.04697 0.96229 1 0.66553 0.06141 0.26763 0.02469 0.14131 0.02841 0.05682 0.01142
