/* ** ** 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 55458.268339 0.001264 0.38745 0.10258 1.00000 1 0.29566 0.04190 0.23762 0.03368 0.11455 0.02562 0.09195 0.02056 55458.270867 0.001264 0.85810 0.26236 0.97701 1 0.13569 0.02829 0.10952 0.02284 0.11644 0.02604 0.09412 0.02105 55458.272857 0.000726 0.64152 0.18332 0.99518 1 0.32413 0.05938 0.26138 0.04789 0.20794 0.04560 0.16802 0.03685 55458.334774 0.001031 0.56920 0.16254 0.98592 1 0.24703 0.04276 0.19826 0.03431 0.14061 0.03194 0.11259 0.02557 55458.336793 0.000988 0.71600 0.20996 0.97059 1 0.21073 0.03997 0.16910 0.03208 0.15088 0.03374 0.12121 0.02710 55458.339364 0.001583 0.54209 0.14148 0.98260 1 0.19649 0.03084 0.15846 0.02487 0.10651 0.02221 0.08590 0.01791
