/* ** ** 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 56108.572913 0.000550 0.13297 0.03168 0.97368 0 1.92902 0.15855 1.62379 0.13347 0.25651 0.05736 0.21658 0.04843 56108.574122 0.000660 0.10296 0.02485 0.97368 0 2.02455 0.14809 1.70925 0.12502 0.20845 0.04795 0.17599 0.04048 56108.575482 0.000700 0.09607 0.02280 0.96281 0 2.09177 0.14674 1.76808 0.12403 0.20096 0.04557 0.16982 0.03851 56108.576570 0.000388 0.16780 0.04110 0.96269 0 2.16159 0.20012 1.82623 0.16907 0.36271 0.08226 0.30673 0.06956 56108.577560 0.000602 0.10683 0.02517 0.98077 0 2.17589 0.16164 1.83981 0.13667 0.23245 0.05198 0.19641 0.04392 56108.578662 0.000501 0.11489 0.02717 0.98266 0 2.43188 0.18719 2.05167 0.15793 0.27941 0.06248 0.23569 0.05270 56108.579849 0.000686 0.08400 0.01957 0.97468 0 2.44391 0.15999 2.06444 0.13515 0.20528 0.04590 0.17345 0.03878 56108.581055 0.000521 0.12925 0.03074 0.96111 0 2.12156 0.17207 1.79213 0.14535 0.27421 0.06132 0.23160 0.05179 56108.582192 0.000616 0.10081 0.02366 0.97653 0 2.26282 0.16159 1.90951 0.13636 0.22812 0.05101 0.19263 0.04307 56108.583399 0.000590 0.12203 0.02589 0.97549 0 2.50986 0.17479 2.10205 0.14638 0.30628 0.06138 0.25673 0.05145
