/* ** ** 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 55473.671396 0.000590 0.10466 0.02497 0.97549 0 2.28559 0.16753 1.89208 0.13863 0.23920 0.05430 0.19869 0.04510 55473.672559 0.000573 0.10289 0.02419 0.97475 0 2.44793 0.17784 2.01484 0.14636 0.25186 0.05632 0.20760 0.04642 55473.673870 0.000738 0.09267 0.02167 0.96471 0 2.12016 0.14497 1.75970 0.12031 0.19647 0.04394 0.16287 0.03642 55473.675045 0.000437 0.16159 0.03902 0.98013 0 2.02959 0.18481 1.67328 0.15235 0.32796 0.07334 0.27072 0.06054 55473.676081 0.000599 0.11352 0.02678 0.96135 0 2.11747 0.15896 1.77063 0.13292 0.24037 0.05375 0.20134 0.04502 55473.677331 0.000651 0.09718 0.02277 0.98222 0 2.24199 0.15710 1.86463 0.13065 0.21788 0.04872 0.18130 0.04054 55473.678560 0.000579 0.10980 0.02630 0.99500 0 2.16237 0.16515 1.80947 0.13819 0.23742 0.05390 0.19869 0.04510 55473.679671 0.000532 0.13219 0.03390 0.98913 0 1.87510 0.16226 1.56058 0.13505 0.24788 0.05983 0.20565 0.04965 55473.680907 0.000703 0.09711 0.02277 0.97942 0 2.06839 0.14610 1.73297 0.12240 0.20086 0.04491 0.16835 0.03764 55473.682229 0.000619 0.10883 0.02564 0.96262 0 2.12723 0.15800 1.78834 0.13283 0.23152 0.05177 0.19450 0.04349 55473.683242 0.000394 0.17249 0.04244 0.98529 0 2.03661 0.19327 1.71017 0.16229 0.35129 0.07974 0.29507 0.06698 55473.684017 0.000382 0.18035 0.04293 0.98485 0 2.13285 0.20278 1.79413 0.17058 0.38466 0.08394 0.32362 0.07062 55473.685236 0.000836 0.08859 0.02024 0.96540 0 2.07208 0.13371 1.74083 0.11233 0.18356 0.04022 0.15419 0.03379
