/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** 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 58175.254516 0.000813 0.23687 0.06047 0.98214 1 2.80923 0.30711 0.59899 0.06547 0.66544 0.15351 0.14131 0.03259 58175.255983 0.000654 0.27153 0.06937 0.97778 1 3.13543 0.37724 0.66260 0.07972 0.85136 0.19188 0.18053 0.04068 58175.257784 0.001148 0.14066 0.03369 0.98734 1 3.43749 0.29501 0.72764 0.06244 0.48352 0.10812 0.10257 0.02293 58175.259426 0.000494 0.41848 0.11342 1.00000 1 2.63973 0.39754 0.55716 0.08391 1.10467 0.24894 0.23362 0.05264 58175.260544 0.000625 0.25365 0.06255 1.00000 1 3.58986 0.40140 0.76191 0.08518 0.91055 0.20014 0.19403 0.04265 58175.262055 0.000886 0.19226 0.04717 1.00000 1 3.22583 0.32557 0.68377 0.06901 0.62018 0.13868 0.13115 0.02933 58175.263638 0.000697 0.21470 0.05305 1.00000 1 3.68467 0.38738 0.77693 0.08168 0.79111 0.17690 0.16667 0.03727 58175.265236 0.000901 0.16876 0.04139 0.96774 1 3.67913 0.34104 0.77811 0.07212 0.62088 0.14099 0.13144 0.02984 58175.267081 0.000944 0.20529 0.04356 0.97995 1 3.90384 0.34867 0.82437 0.07362 0.80142 0.15425 0.16956 0.03263
