/* ** ** 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 56296.816772 0.000538 12.93327 3.59530 0.96774 0 0.23312 0.06263 0.17267 0.04639 3.01495 0.21533 2.21928 0.15845 56296.817817 0.000506 23.46041 8.77208 0.97714 0 0.13466 0.04942 0.09877 0.03624 3.15908 0.22570 2.32178 0.16588 56296.818829 0.000506 15.08225 4.61508 0.96000 0 0.21280 0.06331 0.15694 0.04666 3.20949 0.22965 2.36014 0.16887 56296.819943 0.000602 11.54657 3.00460 0.98558 0 0.22656 0.05664 0.16608 0.04152 2.61605 0.18886 1.91894 0.13853 56296.821124 0.000579 18.69873 6.26708 0.96500 0 0.15133 0.04956 0.11068 0.03624 2.82973 0.20211 2.07478 0.14819 56296.822296 0.000593 11.36099 3.00795 0.96098 0 0.23962 0.06103 0.17616 0.04486 2.72231 0.19689 1.99911 0.14458 56296.823389 0.000501 16.04308 5.09931 0.99422 0 0.19618 0.06075 0.14344 0.04443 3.14728 0.22552 2.30223 0.16497 56296.824417 0.000527 12.95013 3.67048 0.96703 0 0.23625 0.06478 0.17371 0.04763 3.05946 0.21955 2.24695 0.16125 56296.825510 0.000567 10.74171 2.72830 0.95408 0 0.27011 0.06581 0.19674 0.04793 2.90140 0.20822 2.11478 0.15176 56296.826905 0.000828 10.47038 2.28821 0.98601 0 0.25470 0.05344 0.18534 0.03888 2.66684 0.16304 1.94170 0.11871
