/* ** ** 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 56135.498523 0.000654 0.08168 0.01930 0.98673 0 2.52432 0.16541 2.17644 0.14261 0.20618 0.04680 0.17730 0.04025 56135.499478 0.000301 0.17447 0.04233 0.97115 0 2.61134 0.24586 2.27324 0.21403 0.45561 0.10188 0.39670 0.08870 56135.500499 0.000720 0.06673 0.01542 0.98795 0 2.80020 0.16352 2.43938 0.14245 0.18685 0.04178 0.16287 0.03642 56135.501911 0.000692 0.06845 0.01583 0.98326 0 2.86001 0.16845 2.49039 0.14668 0.19577 0.04378 0.17050 0.03812 56135.503147 0.000544 0.10644 0.02506 0.97340 0 2.37142 0.17458 2.05917 0.15160 0.25242 0.05645 0.21894 0.04896 56135.504371 0.000680 0.07726 0.01794 0.97447 0 2.59744 0.16233 2.26414 0.14150 0.20068 0.04487 0.17496 0.03912 56135.505606 0.000556 0.09141 0.02134 0.96354 0 2.72052 0.18217 2.36902 0.15863 0.24867 0.05561 0.21658 0.04843 56135.507244 0.001082 0.05926 0.01221 0.98128 0 2.64580 0.13023 2.29967 0.11319 0.15678 0.03136 0.13647 0.02729
