/* ** ** 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 57287.239728 0.000436 8.29040 5.03905 0.93333 1 0.14110 0.08147 0.04800 0.02771 1.16975 0.22202 0.39856 0.07561 57287.240526 0.000363 3.51098 1.85480 0.96000 1 0.27433 0.13100 0.09398 0.04486 0.96316 0.21764 0.32998 0.07457 57287.241340 0.000450 3.78937 2.07935 0.96774 1 0.20392 0.10196 0.06956 0.03478 0.77272 0.17466 0.26399 0.05966 57287.242386 0.000596 20.49805 14.78506 0.97561 1 0.07087 0.05011 0.02424 0.01714 1.45263 0.20677 0.49698 0.07073 57287.243330 0.000349 17.98289 18.43654 0.95833 1 0.05673 0.05673 0.01905 0.01905 1.02011 0.23058 0.34433 0.07781 57287.244405 0.000726 10.16975 5.43875 0.91568 1 0.11331 0.05819 0.03825 0.01964 1.15238 0.17220 0.39227 0.05861 57287.976871 0.000320 2.82503 1.24424 0.95455 1 0.17408 0.06580 0.13333 0.05039 0.49179 0.11118 0.37700 0.08523
