/* ** ** 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 58228.746402 0.001534 0.09976 0.01853 0.96691 0 1.54754 0.08613 1.27430 0.07091 0.15438 0.02736 0.12694 0.02250 58229.878179 0.000744 0.10895 0.02605 0.98054 0 1.65915 0.12462 1.43574 0.10784 0.18077 0.04103 0.15689 0.03561 58229.879522 0.000599 0.12816 0.03092 0.97585 0 1.77164 0.14466 1.52695 0.12466 0.22705 0.05155 0.19573 0.04443 58229.880624 0.000503 0.15506 0.03735 0.95977 0 1.79845 0.16085 1.55693 0.13924 0.27887 0.06236 0.23992 0.05365 58229.881782 0.000654 0.11303 0.02707 0.98673 0 1.82183 0.13932 1.56531 0.11969 0.20591 0.04674 0.17730 0.04025 58229.882956 0.000521 0.15600 0.03757 0.98333 0 1.68467 0.15068 1.45017 0.12969 0.26281 0.05877 0.22637 0.05062 58229.884447 0.000969 0.07255 0.01706 0.99104 0 1.92712 0.11811 1.64252 0.10065 0.13981 0.03174 0.11909 0.02703 58229.886469 0.001053 0.10206 0.01993 0.98659 0 1.84442 0.11158 1.58819 0.09607 0.18824 0.03496 0.16178 0.03004 58229.939835 0.001687 0.12152 0.02936 0.97942 0 2.22316 0.17542 0.62833 0.04810 0.27015 0.06169 0.07017 0.01569 58229.942972 0.001450 0.14110 0.03393 0.98004 0 2.04826 0.17701 0.57549 0.04960 0.28900 0.06484 0.08160 0.01825 58229.946146 0.001725 0.09586 0.02250 0.97651 0 2.77191 0.19269 0.74269 0.05147 0.26571 0.05958 0.06884 0.01539 58229.949977 0.002106 0.12849 0.02472 0.96978 0 2.55998 0.16996 0.68181 0.04506 0.32892 0.05939 0.08797 0.01580
