/* ** ** 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 56175.897171 0.000625 6.15771 1.19911 0.96759 0 0.36028 0.06533 0.30946 0.05611 2.21850 0.15757 1.90958 0.13563 56175.898462 0.000666 8.09513 1.76994 0.96957 0 0.25577 0.05286 0.22120 0.04571 2.07046 0.14777 1.78700 0.12754 56175.899773 0.000645 11.19909 2.87703 0.97758 0 0.18760 0.04630 0.16279 0.04018 2.10096 0.14988 1.82358 0.13009 56175.901124 0.000706 7.88658 1.67526 0.97541 0 0.24427 0.04886 0.21132 0.04226 1.92649 0.13785 1.66595 0.11920 56175.902452 0.000622 7.26280 1.53823 0.95814 0 0.31240 0.06231 0.26610 0.05306 2.26888 0.16170 1.93700 0.13804 56175.903734 0.000660 6.36141 1.27223 0.96491 0 0.33339 0.06224 0.28445 0.05309 2.12085 0.15211 1.80862 0.12970 56175.905007 0.000613 6.79440 1.36302 0.96698 0 0.33099 0.06210 0.28644 0.05374 2.24890 0.15973 1.94684 0.13827 56175.906630 0.001010 7.00610 1.12289 0.96562 0 0.31303 0.04697 0.27160 0.04075 2.19310 0.12352 1.90285 0.10717
