/* ** ** 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 56153.304503 0.000825 6.40927 1.27873 0.98246 0 0.25694 0.04787 0.22108 0.04119 1.64681 0.11752 1.41946 0.10129 56153.306103 0.000775 7.09316 1.50353 0.98134 0 0.24593 0.04899 0.20993 0.04180 1.74439 0.12642 1.49083 0.10803 56153.307677 0.000799 10.41654 2.50477 0.94203 0 0.16840 0.03864 0.14584 0.03346 1.75419 0.12635 1.51628 0.10920 56153.309268 0.000793 10.46178 2.66935 0.96715 0 0.16763 0.04107 0.14310 0.03505 1.75375 0.12495 1.50183 0.10701 56153.310808 0.000747 7.30879 1.54807 0.97674 0 0.24689 0.04916 0.21334 0.04248 1.80449 0.13036 1.56016 0.11271 56153.312266 0.000712 9.07267 2.06528 0.95935 0 0.21583 0.04665 0.18606 0.04022 1.95817 0.13973 1.68411 0.12018 56153.314454 0.001476 8.15512 1.36840 0.97255 0 0.20397 0.03241 0.17446 0.02772 1.66344 0.08963 1.41921 0.07648
