/* ** ** 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 55363.442423 0.000587 0.11802 0.02798 0.99015 0 1.97310 0.15526 1.67926 0.13213 0.23287 0.05207 0.19934 0.04457 55363.443716 0.000706 0.11829 0.02848 0.99180 0 1.60751 0.12769 1.37629 0.10931 0.19015 0.04322 0.16319 0.03710 55363.445458 0.001036 0.07706 0.01816 0.95531 0 1.76962 0.11061 1.49810 0.09365 0.13637 0.03099 0.11547 0.02625 55363.447284 0.000784 0.10613 0.02576 0.97786 0 1.64373 0.12192 1.38070 0.10240 0.17445 0.04032 0.14686 0.03395 55363.448939 0.000871 0.08128 0.01894 0.98671 0 1.97631 0.12934 1.66103 0.10870 0.16063 0.03592 0.13490 0.03017 55363.450829 0.001019 0.07429 0.01808 0.96875 0 1.77676 0.11158 1.51512 0.09514 0.13200 0.03103 0.11244 0.02643 55363.452432 0.000584 0.12802 0.03045 0.98515 0 1.84088 0.14914 1.57254 0.12739 0.23567 0.05270 0.20134 0.04502 55363.454275 0.001259 0.07086 0.01586 0.96092 0 1.72446 0.09876 1.47001 0.08418 0.12219 0.02644 0.10406 0.02252
