/* ** ** 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 58209.279858 0.000425 0.21354 0.05262 0.97279 0 1.54949 0.16046 1.31081 0.13574 0.33088 0.07399 0.28019 0.06265 58209.281223 0.000940 0.09351 0.02190 0.97538 0 1.59352 0.11075 1.35077 0.09388 0.14901 0.03332 0.12639 0.02826 58209.283020 0.000856 0.10041 0.02356 0.98311 0 1.61262 0.11480 1.37162 0.09764 0.16192 0.03621 0.13769 0.03079 58209.284756 0.000880 0.10378 0.02476 0.97697 0 1.50869 0.11125 1.28353 0.09465 0.15657 0.03553 0.13315 0.03022 58209.286452 0.000816 0.10592 0.02494 0.96809 0 1.62863 0.12000 1.38536 0.10208 0.17250 0.03857 0.14676 0.03282 58209.287887 0.000619 0.13816 0.03298 0.96729 0 1.64710 0.13749 1.40081 0.11694 0.22756 0.05088 0.19356 0.04328 58209.289224 0.000718 0.12156 0.02966 0.99194 0 1.53374 0.12328 1.30517 0.10491 0.18644 0.04294 0.15864 0.03654 58209.290775 0.000833 0.11506 0.02758 0.97569 0 1.43822 0.11105 1.22105 0.09427 0.16548 0.03755 0.14074 0.03194 58209.292395 0.000787 0.10817 0.02548 0.97059 0 1.64977 0.12232 1.40296 0.10402 0.17846 0.03991 0.15177 0.03394 58209.293729 0.000547 0.16279 0.03994 0.98413 0 1.53491 0.14308 1.30610 0.12175 0.24986 0.05670 0.21262 0.04825 58209.295387 0.001105 0.10942 0.02262 0.97120 0 1.50803 0.09857 1.28312 0.08387 0.16501 0.03236 0.14040 0.02753
