/* ** ** 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 53959.308989 0.000087 0.18668 0.06142 0.95254 0 4.73314 0.62368 4.13084 0.54431 0.88356 0.26640 0.77112 0.23250 53959.311484 0.002397 0.09959 0.01672 0.96256 1 3.89460 0.19587 0.98860 0.04972 0.38788 0.06211 0.09822 0.01573 53959.376195 0.000619 0.06172 0.01303 0.97749 0 4.34784 0.21935 3.79524 0.19147 0.26836 0.05501 0.23425 0.04802 53959.444308 0.067484 0.10137 0.01749 0.03022 1 4.02155 0.21056 1.03900 0.05440 0.40767 0.06702 0.10541 0.01733 53959.509727 0.000104 0.09181 0.03927 0.99948 0 4.16902 0.53184 3.63851 0.46416 0.38276 0.15626 0.33405 0.13638
