/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 59406.446912 0.001206 0.21590 0.05522 0.98795 1 2.02548 0.22393 0.43683 0.04828 0.43730 0.10085 0.09477 0.02186 59406.448800 0.000683 0.55789 0.15409 0.95745 1 1.57599 0.26680 0.33486 0.05669 0.87924 0.19188 0.18667 0.04073 59406.451473 0.001990 0.19857 0.04226 0.99060 1 1.87433 0.16585 0.39780 0.03520 0.37218 0.07205 0.07916 0.01532 59406.515352 0.000915 0.25195 0.06420 0.98413 1 2.10439 0.24293 0.50381 0.05814 0.53019 0.12045 0.12719 0.02888 59406.517066 0.000799 0.27800 0.06936 0.98182 1 2.29880 0.27133 0.55714 0.06576 0.63907 0.14048 0.15450 0.03396 59406.518722 0.000857 0.29104 0.07471 0.98305 1 1.95122 0.23985 0.47117 0.05792 0.56788 0.12796 0.13694 0.03086 59406.520901 0.001322 0.24503 0.05122 0.96715 1 2.20736 0.20761 0.53554 0.05037 0.54087 0.10097 0.13115 0.02448
