/* ** ** 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 56019.519101 0.000492 11.57576 3.06249 0.98824 0 0.24705 0.06290 0.20350 0.05180 2.85978 0.20549 2.35152 0.16894 56019.520140 0.000547 15.68135 4.66373 0.96296 0 0.16844 0.04862 0.13896 0.04011 2.64135 0.18894 2.17904 0.15587 56019.521187 0.000495 21.11966 7.19845 0.98246 0 0.13642 0.04547 0.11269 0.03756 2.88118 0.20498 2.37863 0.16922 56019.522220 0.000538 11.31841 2.95353 0.96774 0 0.23679 0.05943 0.19548 0.04906 2.68006 0.19150 2.21155 0.15802 56019.523259 0.000501 13.50549 3.89532 0.97688 0 0.21254 0.05938 0.17290 0.04831 2.87045 0.20592 2.34062 0.16791 56019.524329 0.000570 13.68709 3.93942 0.96954 0 0.18319 0.05105 0.15098 0.04207 2.50735 0.18066 2.06301 0.14864 56019.525501 0.000602 14.45964 4.14200 0.98077 0 0.16291 0.04518 0.13424 0.03723 2.35563 0.16875 1.94155 0.13908 56019.526665 0.000561 11.06661 2.84488 0.96907 0 0.22972 0.05667 0.18953 0.04676 2.54228 0.18377 2.09573 0.15149 56019.527695 0.000469 31.08964 12.88309 0.98765 0 0.09783 0.03994 0.08067 0.03293 3.04157 0.21609 2.50075 0.17766 56019.528745 0.000582 13.67704 3.93448 0.98507 0 0.17827 0.04967 0.14688 0.04093 2.43817 0.17447 2.00792 0.14368 56019.529923 0.000596 13.77964 3.80823 0.98544 0 0.18005 0.04812 0.14840 0.03966 2.48100 0.17455 2.03723 0.14332
