/* ** ** Swift/XRT hardness ratio for Cen A. ** 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 56075.459590 0.000645 10.76363 2.69392 0.95067 0 0.20513 0.04918 0.17334 0.04154 2.20794 0.15848 1.86512 0.13387 56075.460877 0.000642 14.15730 4.25347 0.97297 0 0.15195 0.04433 0.12971 0.03785 2.15123 0.15424 1.83742 0.13174 56075.462208 0.000689 7.17166 1.53161 0.96639 0 0.28191 0.05674 0.24067 0.04844 2.02175 0.14446 1.72602 0.12333 56075.463548 0.000651 16.24708 4.94576 0.99111 0 0.12982 0.03842 0.11091 0.03283 2.10919 0.15001 1.80243 0.12819 56075.464862 0.000663 8.83044 2.05596 0.97817 0 0.23299 0.05157 0.19877 0.04400 2.05742 0.14856 1.75581 0.12678 56075.466132 0.000608 13.57465 3.83091 0.97143 0 0.16840 0.04598 0.14334 0.03914 2.28593 0.16309 1.94858 0.13902 56075.467330 0.000590 12.08740 3.25358 0.97549 0 0.19510 0.05065 0.16667 0.04327 2.35829 0.16765 2.01503 0.14325 56075.468612 0.000692 9.59871 2.34960 0.97490 0 0.20658 0.04834 0.17655 0.04131 1.98290 0.14254 1.69476 0.12182 56075.470053 0.000749 7.46472 1.57015 0.99228 0 0.26841 0.05341 0.22931 0.04563 2.00362 0.13653 1.71169 0.11664
