/* ** ** 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 59686.813598 0.000973 0.10750 0.02528 0.97015 1 4.65289 0.33884 1.14002 0.08301 0.50016 0.11186 0.12308 0.02752 59686.815312 0.000741 0.14859 0.03568 1.00000 1 4.39967 0.38469 1.05582 0.09231 0.65373 0.14618 0.15686 0.03508 59686.816823 0.000770 0.14095 0.03372 0.98113 1 4.53560 0.38582 1.09556 0.09320 0.63929 0.14297 0.15385 0.03440 59686.818479 0.000886 0.10472 0.02518 0.98361 1 5.18793 0.38091 1.24554 0.09145 0.54326 0.12440 0.13041 0.02986 59686.820454 0.001089 0.07919 0.01842 1.00000 1 5.55767 0.35564 1.34930 0.08634 0.44013 0.09842 0.10667 0.02385 59686.822226 0.000683 0.14457 0.03495 1.00000 1 4.80420 0.41962 1.17443 0.10256 0.69454 0.15658 0.16897 0.03808 59686.823824 0.000915 0.10009 0.02351 1.00000 1 5.22651 0.37550 1.27145 0.09134 0.52315 0.11700 0.12699 0.02839 59686.826235 0.001496 0.13228 0.02283 0.96809 1 4.71230 0.27720 1.15510 0.06795 0.62333 0.10113 0.15244 0.02473
