/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 57620.628105 0.000631 0.10858 0.02633 0.97248 0 2.10192 0.15911 1.69110 0.12800 0.22823 0.05258 0.18404 0.04241 57620.629404 0.000668 0.11384 0.02691 0.94805 0 2.01077 0.15406 1.60441 0.12291 0.22890 0.05119 0.18295 0.04091 57620.630750 0.000677 0.11073 0.02729 0.97009 0 1.88052 0.14585 1.52991 0.11866 0.20823 0.04872 0.16956 0.03967 57620.632266 0.000839 0.08109 0.01888 0.97586 0 2.14476 0.13926 1.74438 0.11326 0.17391 0.03889 0.14158 0.03166 57620.633522 0.000417 0.20310 0.05008 0.97222 0 1.73698 0.18039 1.40880 0.14628 0.35278 0.07889 0.28619 0.06399 57620.634439 0.000501 0.12981 0.03140 0.95954 0 2.25246 0.18855 1.83499 0.15360 0.29240 0.06636 0.23820 0.05406 57620.635860 0.000920 0.11491 0.02381 0.96435 0 1.81808 0.12147 1.47755 0.09871 0.20892 0.04097 0.16985 0.03331
