/* ** ** 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 56498.463174 0.000349 9.77917 4.73366 0.95833 1 0.34334 0.15875 0.08820 0.04075 3.35761 0.48098 0.85919 0.12309 56498.463857 0.000334 11.45242 6.17838 0.95652 1 0.31647 0.16484 0.08107 0.04222 3.62429 0.50911 0.92457 0.12987 56498.464525 0.000334 12.08720 7.18761 0.95652 1 0.29112 0.16808 0.07500 0.04330 3.51881 0.50087 0.90367 0.12862 56498.465164 0.000305 8.91892 4.18727 1.00000 1 0.41294 0.18468 0.10526 0.04708 3.68295 0.52595 0.94386 0.13478 56498.465861 0.000392 8.49407 3.98637 1.00000 1 0.34427 0.15397 0.08696 0.03889 2.92422 0.41600 0.74450 0.10592 56498.466573 0.000320 5.43016 2.10582 1.00000 1 0.65197 0.23519 0.16528 0.05963 3.54029 0.50393 0.90367 0.12862 56498.467241 0.000349 26.68319 19.20376 0.95833 1 0.14227 0.10060 0.03636 0.02571 3.79613 0.50874 0.97132 0.13017 56498.467997 0.000378 7.30763 3.15469 1.00000 1 0.42661 0.17417 0.10909 0.04454 3.11752 0.43748 0.79931 0.11217 56498.468694 0.000320 12.60230 6.80092 1.00000 1 0.28669 0.14931 0.07335 0.03820 3.61295 0.51075 0.91914 0.12993 56498.469667 0.000654 33.53645 21.91038 1.00000 1 0.11377 0.07352 0.02920 0.01886 3.81535 0.36744 0.97340 0.09374 56498.470640 0.000320 20.52572 14.80135 1.00000 1 0.17377 0.12287 0.04444 0.03143 3.56672 0.50442 0.90910 0.12857 56498.471352 0.000392 9.06455 4.25930 0.96296 1 0.32645 0.14599 0.08333 0.03727 2.95912 0.42668 0.75546 0.10893 56498.472122 0.000378 10.95031 5.69283 0.96154 1 0.28467 0.14234 0.07273 0.03636 3.11718 0.44370 0.79523 0.11319
