/* ** ** 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 56820.269890 0.000816 0.12588 0.03001 0.98582 0 1.59540 0.12862 1.16125 0.09327 0.20082 0.04507 0.14412 0.03223 56820.271647 0.000940 0.09364 0.02192 0.97846 0 1.76685 0.12252 1.35086 0.09367 0.16545 0.03700 0.12600 0.02817 56820.273585 0.000998 0.08326 0.01967 0.98551 0 1.82004 0.11968 1.39776 0.09192 0.15153 0.03438 0.11633 0.02639 56820.275400 0.000816 0.10955 0.02695 0.97872 0 1.67668 0.12877 1.27906 0.09822 0.18369 0.04293 0.13958 0.03262 56820.277075 0.000859 0.10595 0.02531 0.97980 0 1.67652 0.12527 1.28578 0.09607 0.17763 0.04030 0.13592 0.03084 56820.278817 0.000883 0.09802 0.02302 0.98033 0 1.78866 0.12811 1.36807 0.09797 0.17533 0.03921 0.13400 0.02996
