/* ** ** 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 53957.968247 0.000365 0.12508 0.01877 0.99206 0 7.24381 0.36279 6.48622 0.32484 0.90606 0.12817 0.81049 0.11466 53957.968955 0.000344 0.12845 0.01930 0.97479 0 7.51339 0.38061 6.73761 0.34133 0.96510 0.13649 0.86350 0.12212 53957.969609 0.000310 0.14003 0.02137 0.99065 0 7.45800 0.39938 6.70388 0.35901 1.04438 0.14924 0.93687 0.13388 53957.970749 0.000830 0.10211 0.01088 0.96877 0 7.68592 0.24713 6.88865 0.22149 0.78480 0.07971 0.70303 0.07139 53957.972257 0.000668 0.11086 0.02611 0.97826 1 6.25754 0.46349 1.60685 0.11902 0.69370 0.15512 0.17778 0.03975 53957.973608 0.000683 0.11016 0.02537 1.00000 1 6.31214 0.46435 1.61712 0.11896 0.69533 0.15174 0.17872 0.03900 53957.974784 0.000494 0.14487 0.03500 1.00000 1 6.26595 0.54520 1.61352 0.14038 0.90773 0.20460 0.23356 0.05264 53957.975670 0.000392 0.20370 0.05022 1.00000 1 5.64207 0.58555 1.45423 0.15091 1.14930 0.25700 0.29630 0.06625 53957.976527 0.000465 0.14490 0.03475 1.00000 1 6.78334 0.58728 1.73243 0.14998 0.98290 0.21980 0.25000 0.05590 53957.978416 0.001423 0.09844 0.01687 0.95257 1 6.43764 0.32818 1.63859 0.08353 0.63370 0.10366 0.16156 0.02643
