/* ** ** 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 56015.979264 0.000518 11.80719 3.06921 0.97765 0 0.22755 0.05689 0.19309 0.04827 2.68671 0.19112 2.28379 0.16245 56015.980337 0.000556 7.75277 1.67994 0.99479 0 0.31441 0.06433 0.26820 0.05487 2.43757 0.17384 2.08199 0.14847 56015.981353 0.000460 8.08925 1.80351 0.98742 0 0.37072 0.07827 0.31216 0.06590 2.99881 0.21479 2.52329 0.18071 56015.982334 0.000521 13.31213 3.68188 0.98889 0 0.19773 0.05285 0.16896 0.04516 2.63219 0.18727 2.24530 0.15971 56015.983399 0.000544 11.64187 3.02765 0.97872 0 0.21720 0.05430 0.18636 0.04659 2.52856 0.18116 2.15847 0.15462 56015.984405 0.000463 10.48744 2.58865 0.95000 0 0.29516 0.06978 0.25212 0.05960 3.09547 0.21959 2.63596 0.18697 56015.985337 0.000469 5.76991 1.09258 0.99383 0 0.50416 0.08852 0.43164 0.07578 2.90897 0.20634 2.48861 0.17652 56015.986362 0.000556 6.75657 1.37798 0.99479 0 0.35942 0.06862 0.30714 0.05863 2.42846 0.17417 2.07150 0.14856 56015.987464 0.000547 9.40319 2.23577 0.99471 0 0.26212 0.05945 0.22480 0.05098 2.46475 0.17603 2.11255 0.15086 56015.988448 0.000437 11.39186 2.96946 0.98675 0 0.27489 0.06894 0.23610 0.05922 3.13150 0.22237 2.67895 0.19023 56015.989565 0.000680 11.84904 2.51802 1.00000 0 0.25711 0.05260 0.22109 0.04523 3.04652 0.17510 2.61498 0.15029
