/* ** ** 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 55715.745908 0.000883 0.11031 0.02605 0.98361 0 1.40432 0.10652 1.21138 0.09189 0.15491 0.03464 0.13356 0.02986 55715.747610 0.000819 0.12494 0.02965 0.98233 0 1.34435 0.10669 1.16107 0.09215 0.16796 0.03756 0.14412 0.03223 55715.749476 0.001047 0.09535 0.02265 0.97514 0 1.35747 0.09497 1.17462 0.08217 0.12943 0.02939 0.11198 0.02543 55715.751536 0.001013 0.10318 0.02535 0.97143 0 1.27026 0.09315 1.09603 0.08037 0.13107 0.03073 0.11309 0.02649 55715.753724 0.001175 0.08234 0.01944 0.95074 0 1.43197 0.09237 1.24403 0.08024 0.11791 0.02677 0.10241 0.02325 55715.755917 0.001019 0.14584 0.02906 0.97159 0 1.34186 0.09695 1.16362 0.08407 0.19570 0.03634 0.16987 0.03154
