/* ** ** 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 56563.955520 0.001317 0.08301 0.02049 0.94725 0 1.27763 0.08491 1.05955 0.07042 0.10605 0.02521 0.08801 0.02093 56563.957743 0.000906 0.11791 0.02796 0.95208 0 1.37163 0.10832 1.14027 0.09005 0.16173 0.03617 0.13445 0.03006 56563.959479 0.000830 0.11491 0.02759 0.96864 0 1.48940 0.11621 1.23675 0.09650 0.17114 0.03886 0.14220 0.03228 56563.961085 0.000775 0.14673 0.03572 0.97388 0 1.23986 0.10907 1.03193 0.09078 0.18192 0.04130 0.15147 0.03439 56563.962586 0.000726 0.15944 0.03894 0.96016 0 1.23769 0.11142 1.02959 0.09268 0.19734 0.04480 0.16404 0.03724 56563.964076 0.000764 0.14405 0.03500 0.96591 0 1.29554 0.11208 1.07696 0.09318 0.18662 0.04237 0.15503 0.03520 56563.965465 0.000625 0.16731 0.04102 0.98148 0 1.34093 0.12418 1.11444 0.10321 0.22435 0.05094 0.18648 0.04234 56563.966736 0.000645 0.17540 0.04151 0.97758 0 1.32484 0.12125 1.10030 0.10070 0.23238 0.05071 0.19298 0.04211 56563.968182 0.000802 0.12218 0.02901 0.97473 0 1.46538 0.11681 1.21420 0.09678 0.17904 0.04004 0.14840 0.03318 56563.969652 0.000668 0.15518 0.03840 0.97835 0 1.33728 0.12029 1.11238 0.10006 0.20752 0.04784 0.17256 0.03978 56563.971053 0.000732 0.14270 0.03419 0.98419 0 1.35589 0.11661 1.12750 0.09697 0.19348 0.04326 0.16091 0.03598 56563.972682 0.000897 0.16470 0.03363 0.96774 0 1.36332 0.10537 1.13501 0.08772 0.22454 0.04243 0.18698 0.03534
