/* ** ** 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 57483.777505 0.000558 0.16839 0.02564 0.93782 0 4.17056 0.23982 3.29754 0.18880 0.70226 0.09901 0.56162 0.07909 57483.778544 0.000480 0.18276 0.02841 0.96988 0 4.27674 0.25946 3.38212 0.20516 0.78163 0.11186 0.61573 0.08810 57483.779600 0.000576 0.11255 0.01903 0.98492 0 4.46799 0.24217 3.52710 0.19115 0.50286 0.08053 0.39862 0.06383 57483.780737 0.000561 0.13738 0.02095 0.96392 0 4.87775 0.25668 3.86554 0.20340 0.67011 0.09589 0.53012 0.07585 57483.781883 0.000584 0.11918 0.02021 0.97030 0 4.22753 0.23538 3.34446 0.18620 0.50385 0.08069 0.39862 0.06383 57483.783127 0.000660 0.11979 0.01825 0.97807 0 4.68860 0.23401 3.68357 0.18384 0.56165 0.08085 0.44223 0.06365 57483.784316 0.000530 0.15112 0.02306 0.96175 0 4.88086 0.26648 3.78014 0.20638 0.73760 0.10509 0.57170 0.08145 57483.785167 0.000321 0.10249 0.02411 0.99099 0 4.55016 0.33308 3.56036 0.26060 0.46633 0.10428 0.36424 0.08145 57483.786076 0.000587 0.13893 0.02100 0.98522 0 4.59550 0.24548 3.61046 0.19286 0.63847 0.09030 0.50083 0.07083 57483.786955 0.000292 0.12290 0.02917 1.00000 0 4.09989 0.32670 3.23832 0.25801 0.50386 0.11267 0.39670 0.08870 57483.787638 0.000391 0.20569 0.03164 0.97778 0 4.85301 0.30893 3.76082 0.23940 0.99820 0.13978 0.77402 0.10838 57483.788651 0.000622 0.14077 0.02152 0.98605 0 4.26457 0.22927 3.33798 0.17944 0.60033 0.08589 0.46761 0.06691 57483.789678 0.000405 0.07786 0.01834 0.97143 0 4.78434 0.30355 3.72871 0.23660 0.37253 0.08451 0.29081 0.06599 57483.790569 0.000486 0.18697 0.02897 0.97619 0 4.19812 0.25807 3.25587 0.20014 0.78492 0.11166 0.60762 0.08643 57483.791547 0.000492 0.18969 0.02958 0.96471 0 4.10928 0.25482 3.19212 0.19794 0.77951 0.11153 0.60447 0.08649 57483.792427 0.000388 0.11517 0.02412 0.97761 0 4.38256 0.29486 3.41323 0.22963 0.50473 0.10009 0.39366 0.07808 57483.793266 0.000451 0.17584 0.02688 0.99359 0 4.83019 0.28480 3.76320 0.22189 0.84933 0.11978 0.66208 0.09338
