/* ** ** 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 56817.276066 0.000747 0.06902 0.01596 0.96512 0 2.69988 0.15862 2.32221 0.13643 0.18635 0.04167 0.16091 0.03598 56817.277452 0.000639 0.08177 0.01961 0.99095 0 2.54490 0.16859 2.18076 0.14445 0.20809 0.04797 0.17802 0.04106 56817.278632 0.000541 0.10394 0.02386 0.97861 0 2.61243 0.18627 2.20986 0.15755 0.27152 0.05925 0.22989 0.05017 56817.279819 0.000645 0.08132 0.01920 0.97758 0 2.63681 0.17038 2.22914 0.14403 0.21441 0.04869 0.18131 0.04117 56817.281219 0.000755 0.07278 0.01686 0.95785 0 2.60043 0.15696 2.19364 0.13240 0.18925 0.04232 0.16027 0.03584 56817.282504 0.000530 0.10094 0.02408 0.99454 0 2.53820 0.18574 2.15258 0.15752 0.25622 0.05818 0.21718 0.04932 56817.283690 0.000657 0.08004 0.01890 0.98238 0 2.61326 0.16829 2.21533 0.14267 0.20918 0.04751 0.17725 0.04025 56817.284854 0.000506 0.10586 0.02527 0.96571 0 2.61191 0.19216 2.21143 0.16270 0.27650 0.06279 0.23388 0.05311 56817.285985 0.000625 0.10922 0.02257 0.97685 0 2.66653 0.17368 2.26074 0.14724 0.29124 0.05712 0.24686 0.04841
