/* ** ** 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 55708.116989 0.000674 0.10537 0.02514 0.95708 0 1.94288 0.14261 1.67929 0.12326 0.20472 0.04648 0.17728 0.04025 55708.118331 0.000668 0.11912 0.02861 0.95238 0 1.72863 0.13572 1.50819 0.11841 0.20591 0.04675 0.17970 0.04080 55708.120094 0.001094 0.06903 0.01620 0.96031 0 1.80905 0.10760 1.57728 0.09381 0.12488 0.02835 0.10891 0.02472 55708.122044 0.000856 0.09970 0.02373 0.96961 0 1.58761 0.11352 1.37945 0.09863 0.15828 0.03593 0.13775 0.03127 55708.123745 0.000845 0.08661 0.02051 0.98973 0 1.82320 0.12264 1.58185 0.10641 0.15791 0.03585 0.13680 0.03106 55708.125363 0.000773 0.09810 0.02299 0.97378 0 1.80956 0.12671 1.56664 0.10969 0.17752 0.03970 0.15410 0.03446 55708.127987 0.001852 0.07200 0.01226 0.95938 0 1.94609 0.08634 1.67653 0.07438 0.14012 0.02304 0.12072 0.01985
