/* ** ** 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 56543.216427 0.000547 0.17343 0.04210 0.93651 0 2.13401 0.19737 1.37052 0.12636 0.37011 0.08306 0.22637 0.05062 56543.217575 0.000602 0.14258 0.03507 0.98077 0 2.30542 0.19963 1.34809 0.11673 0.32871 0.07568 0.19132 0.04406 56543.218559 0.000382 0.23352 0.05820 0.97727 0 2.28118 0.25109 1.32169 0.14548 0.53269 0.11913 0.31059 0.06945 56543.219789 0.000848 0.09617 0.02256 0.98294 0 2.48162 0.17581 1.44494 0.10234 0.23866 0.05338 0.13912 0.03111 56543.221435 0.000793 0.11776 0.02788 0.96715 0 2.22512 0.17292 1.28360 0.09973 0.26204 0.05860 0.15119 0.03381 56543.944097 0.000579 0.17282 0.04249 0.97500 0 1.44551 0.13636 1.17558 0.11085 0.24982 0.05671 0.20278 0.04602 56543.945492 0.000816 0.14061 0.03368 0.97470 0 1.26888 0.10879 1.04142 0.08928 0.17842 0.03990 0.14577 0.03259 56543.947026 0.000718 0.15207 0.03651 0.95161 0 1.35834 0.11873 1.12091 0.09797 0.20656 0.04619 0.16977 0.03796 56543.948524 0.000781 0.15227 0.03666 0.98148 0 1.20786 0.10773 0.99120 0.08840 0.18393 0.04113 0.15119 0.03381 56543.950151 0.000845 0.12190 0.02895 0.97945 0 1.38728 0.11087 1.14971 0.09189 0.16911 0.03781 0.14009 0.03133 56543.952575 0.001580 0.11126 0.02050 0.97253 0 1.39328 0.08050 1.14996 0.06644 0.15502 0.02712 0.12809 0.02241
