/* ** ** 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 56518.969681 0.000373 0.13254 0.03198 0.98450 0 2.75015 0.22442 2.34793 0.19160 0.36450 0.08277 0.31122 0.07067 56518.970369 0.000315 0.16067 0.03868 0.96330 0 2.78919 0.24873 2.36767 0.21112 0.44813 0.10021 0.38159 0.08533 56518.971153 0.000469 0.10709 0.02521 0.98148 0 2.74347 0.20207 2.34830 0.17296 0.29380 0.06570 0.25199 0.05635 56518.971961 0.000339 0.14159 0.03435 0.99145 0 2.79785 0.23873 2.40710 0.20539 0.39614 0.08995 0.34074 0.07738 56518.972658 0.000359 0.13664 0.03266 0.99194 0 2.78095 0.23509 2.38463 0.20157 0.37998 0.08497 0.32575 0.07284 56518.973517 0.000501 0.09607 0.02253 0.98844 0 2.84148 0.20038 2.43587 0.17176 0.27299 0.06104 0.23431 0.05239 56518.974351 0.000333 0.16476 0.03987 0.97391 0 2.53870 0.23497 2.16923 0.20076 0.41828 0.09353 0.35774 0.07999 56518.975039 0.000356 0.13741 0.03279 0.98374 0 2.85880 0.23831 2.43154 0.20266 0.39282 0.08784 0.33113 0.07404 56518.975774 0.000379 0.14262 0.03461 0.96183 0 2.57682 0.22083 2.20747 0.18919 0.36751 0.08345 0.31369 0.07123 56518.976527 0.000373 0.13506 0.03411 0.96899 0 2.63400 0.22239 2.24593 0.18958 0.35575 0.08467 0.30322 0.07219 56518.977253 0.000353 0.14943 0.03585 0.98361 0 2.62153 0.22785 2.23447 0.19420 0.39174 0.08760 0.33389 0.07466 56518.978367 0.000761 0.12007 0.02256 0.97338 0 2.47107 0.15282 2.11637 0.13087 0.29671 0.05265 0.25401 0.04505
