/* ** ** 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 57668.603929 0.001114 0.10377 0.02556 0.98182 0 1.15188 0.08582 0.97923 0.07295 0.11953 0.02807 0.10155 0.02384 57668.605806 0.000764 0.16117 0.04010 0.98106 0 1.09649 0.10144 0.93543 0.08654 0.17672 0.04081 0.15037 0.03473 57668.607855 0.001285 0.08111 0.01917 0.97523 0 1.32435 0.08617 1.12861 0.07342 0.10742 0.02440 0.09124 0.02073 57668.610014 0.000868 0.13252 0.03156 0.97000 0 1.21928 0.09994 1.03679 0.08498 0.16158 0.03613 0.13769 0.03079 57668.611753 0.000871 0.12571 0.03036 0.96678 0 1.26428 0.10336 1.07691 0.08801 0.15894 0.03612 0.13576 0.03085 57668.613587 0.000964 0.14637 0.03322 0.97297 0 1.13476 0.09353 0.96114 0.07921 0.16609 0.03513 0.14048 0.02970
