/* ** ** 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 56149.831436 0.000943 10.04676 2.41576 0.96319 0 0.15249 0.03499 0.12439 0.02854 1.53201 0.11014 1.25764 0.09040 56149.833311 0.000932 12.01827 3.17952 0.96894 0 0.12799 0.03260 0.10616 0.02704 1.53820 0.11012 1.27380 0.09119 56149.835152 0.000909 8.49116 1.91147 0.97134 0 0.18484 0.03941 0.15250 0.03251 1.56952 0.11333 1.28959 0.09311 56149.836966 0.000906 8.08066 1.80904 0.95527 0 0.19696 0.04173 0.16261 0.03446 1.59154 0.11510 1.31371 0.09500 56149.838806 0.000935 6.07837 1.21907 0.92879 0 0.25897 0.04845 0.21541 0.04030 1.57409 0.11366 1.31108 0.09466 56149.841274 0.001534 5.55154 0.88401 0.90377 0 0.27409 0.04056 0.22841 0.03381 1.52160 0.08941 1.26926 0.07458
