/* ** ** 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 56798.692299 0.000883 0.13754 0.01054 0.99344 0 10.52529 0.28005 9.49124 0.25254 1.44765 0.10403 1.30542 0.09381 56798.694121 0.000940 0.14113 0.01079 0.98462 0 9.73775 0.26043 8.78107 0.23484 1.37429 0.09844 1.23927 0.08877 56798.696150 0.001088 0.14110 0.00969 0.97223 0 10.57113 0.25301 9.53257 0.22816 1.49162 0.09596 1.34508 0.08653 56798.757136 0.001105 0.16652 0.01282 0.98429 0 11.28923 0.33092 6.36645 0.18662 1.87984 0.13379 1.06012 0.07545 56798.758574 0.000327 0.16371 0.02590 0.97345 0 9.55873 0.55699 5.39055 0.31411 1.56486 0.23016 0.88249 0.12980 56798.759225 0.000324 0.18159 0.02798 0.96429 0 9.05659 0.55423 5.10737 0.31255 1.64462 0.23258 0.92747 0.13116 56798.759870 0.000321 0.18450 0.02810 0.95495 0 9.26378 0.55434 5.22422 0.31262 1.70917 0.23933 0.96387 0.13497 56798.760605 0.000414 0.11252 0.01744 0.97902 0 10.92767 0.53312 6.16255 0.30065 1.22954 0.18084 0.69338 0.10198 56798.761424 0.000405 0.16490 0.02165 0.98062 0 10.74638 0.53372 6.06032 0.30098 1.77210 0.21535 0.99936 0.12144 56798.826889 0.000692 0.16002 0.01248 0.98326 0 11.22966 0.32103 10.46580 0.29919 1.79696 0.13037 1.67473 0.12150 56798.828220 0.000639 0.16843 0.01327 0.99548 0 11.34505 0.33533 10.57334 0.31252 1.91081 0.13953 1.78084 0.13004 56798.829617 0.000758 0.14669 0.01146 0.99618 0 10.97959 0.30427 10.23274 0.28358 1.61065 0.11761 1.50109 0.10961 56798.831145 0.000770 0.14780 0.01119 0.98496 0 11.21944 0.30512 10.45628 0.28436 1.65821 0.11712 1.54542 0.10915
