/* ** ** 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 56483.670162 0.000755 0.15971 0.03851 0.95785 0 1.18080 0.10640 1.00328 0.09039 0.18859 0.04217 0.16027 0.03584 56483.671945 0.001027 0.10286 0.02454 0.96901 0 1.32511 0.09681 1.11926 0.08176 0.13630 0.03095 0.11492 0.02609 56483.673939 0.000966 0.10044 0.02331 0.97006 0 1.49294 0.10407 1.27661 0.08899 0.14994 0.03320 0.12820 0.02838 56483.675886 0.000981 0.11584 0.02779 0.98525 0 1.20032 0.09317 1.02095 0.07924 0.13904 0.03157 0.11836 0.02687 56483.677689 0.000822 0.12612 0.02996 0.97535 0 1.33805 0.10728 1.14323 0.09165 0.16875 0.03773 0.14465 0.03234 56483.679465 0.000955 0.12095 0.02865 0.96061 0 1.21739 0.09524 1.04527 0.08177 0.14724 0.03292 0.12639 0.02826
