/* ** ** 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 56598.203232 0.000697 0.66761 0.18900 1.00000 1 0.34981 0.06305 0.26298 0.04739 0.23354 0.05098 0.17500 0.03819 56598.204786 0.000857 0.57934 0.16457 1.00000 1 0.30780 0.05392 0.23429 0.04105 0.17832 0.03988 0.13559 0.03032 56598.206471 0.000828 0.61718 0.17818 1.00000 1 0.30207 0.05516 0.22642 0.04134 0.18643 0.04169 0.14035 0.03138 56598.208098 0.000799 0.71057 0.20362 0.98182 1 0.28939 0.05374 0.21887 0.04064 0.20563 0.04488 0.15556 0.03395 56598.209666 0.000770 0.59683 0.16914 1.00000 1 0.33498 0.05832 0.25385 0.04419 0.19993 0.04471 0.15094 0.03375 56598.211279 0.000842 0.53001 0.14858 1.00000 1 0.33829 0.05610 0.25755 0.04270 0.17930 0.04053 0.13655 0.03086 56598.212949 0.000828 0.57873 0.16561 1.00000 1 0.32245 0.05757 0.24385 0.04354 0.18661 0.04173 0.14035 0.03138 56598.215215 0.001438 0.65509 0.15096 0.96022 1 0.26348 0.03803 0.19794 0.02857 0.17260 0.03100 0.13044 0.02343
