/* ** ** 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 55097.354949 0.000891 0.11976 0.02837 0.97078 0 1.43445 0.11214 1.11996 0.08755 0.17179 0.03842 0.13400 0.02996 55097.356702 0.000862 0.09609 0.02284 0.98322 0 1.81864 0.12909 1.40407 0.09965 0.17475 0.03965 0.13498 0.03063 55097.358679 0.001114 0.08564 0.01997 0.96883 0 1.61998 0.10704 1.25085 0.08265 0.13873 0.03102 0.10742 0.02402 55097.360626 0.000833 0.13067 0.03111 0.97569 0 1.40872 0.11526 1.09092 0.08926 0.18407 0.04116 0.14259 0.03188 55097.362070 0.000611 0.15578 0.03706 0.97156 0 1.66696 0.14550 1.29848 0.11334 0.25968 0.05746 0.20269 0.04485 55097.363653 0.000972 0.09162 0.02174 0.97619 0 1.70340 0.11857 1.31349 0.09144 0.15607 0.03541 0.12057 0.02736 55097.365380 0.000755 0.11881 0.02932 0.98084 0 1.63891 0.13013 1.27168 0.10095 0.19471 0.04550 0.15044 0.03517 55097.367093 0.000958 0.13038 0.02721 0.96979 0 1.62280 0.11581 1.24539 0.08887 0.21158 0.04150 0.16226 0.03182
