/* ** ** 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 57661.355144 0.000663 0.16420 0.02693 0.98690 0 2.82992 0.17362 2.38530 0.14635 0.46467 0.07069 0.39183 0.05960 57661.356151 0.000344 0.14920 0.03335 0.97479 0 3.16358 0.25478 2.66333 0.21446 0.47202 0.09843 0.39721 0.08282 57661.356996 0.000495 0.11351 0.02679 0.97661 0 2.53009 0.19110 2.11584 0.15981 0.28719 0.06422 0.23992 0.05365 57661.357925 0.000434 0.09610 0.02254 1.00000 0 3.28237 0.23265 2.77645 0.19680 0.31543 0.07054 0.26711 0.05973 57661.358851 0.000492 0.10753 0.02573 0.97647 0 2.65115 0.19996 2.21662 0.16717 0.28507 0.06473 0.23816 0.05407 57661.359658 0.000315 0.18990 0.04827 0.96330 0 2.30623 0.22967 1.93107 0.19230 0.43795 0.10243 0.36638 0.08578 57661.360312 0.000339 0.12757 0.03039 1.00000 0 3.20842 0.26356 2.69283 0.22120 0.40929 0.09153 0.34245 0.07657 57661.360983 0.000333 0.14289 0.03258 0.96522 0 3.32329 0.26833 2.77974 0.22442 0.47487 0.10125 0.39706 0.08465 57661.361712 0.000396 0.11372 0.02765 0.99270 0 2.96787 0.22966 2.52169 0.19513 0.33751 0.07779 0.28678 0.06611 57661.362404 0.000295 0.15040 0.03717 0.99020 0 3.08080 0.27382 2.56301 0.22778 0.46336 0.10684 0.38616 0.08902 57661.363619 0.000920 0.19793 0.02667 0.96855 0 2.59565 0.14444 2.18672 0.12167 0.51375 0.06305 0.43406 0.05327
