/* ** ** 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 56007.289147 0.000634 12.59422 3.50851 0.97717 0 0.17186 0.04626 0.14702 0.03958 2.16443 0.15529 1.85368 0.13299 56007.290305 0.000524 11.55172 3.02289 0.98895 0 0.22346 0.05623 0.19168 0.04823 2.58140 0.18548 2.21309 0.15902 56007.291509 0.000680 7.96166 1.74803 0.97872 0 0.25336 0.05261 0.21727 0.04512 2.01715 0.14396 1.72784 0.12332 56007.292889 0.000700 6.65992 1.36759 0.97107 0 0.29515 0.05678 0.25278 0.04863 1.96570 0.14117 1.68182 0.12078 56007.294168 0.000579 11.62597 3.13479 0.98000 0 0.20286 0.05274 0.17396 0.04523 2.35843 0.16884 2.02202 0.14476 56007.295354 0.000608 12.26559 3.37202 0.97143 0 0.18296 0.04852 0.15681 0.04159 2.24405 0.16243 1.92406 0.13926 56007.296581 0.000619 14.89857 4.54286 0.96262 0 0.14965 0.04434 0.12839 0.03804 2.22961 0.16062 1.91330 0.13784 56007.297782 0.000582 9.87711 2.40913 0.97015 0 0.24045 0.05607 0.20615 0.04807 2.37495 0.16977 2.03518 0.14548 56007.299165 0.000802 10.65593 2.35496 0.98556 0 0.21766 0.04620 0.18654 0.03960 2.31941 0.14263 1.98750 0.12222
