/* ** ** 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 56155.446522 0.000929 11.31913 2.91756 0.96262 0 0.13235 0.03275 0.11206 0.02775 1.49804 0.10798 1.27499 0.09188 56155.448246 0.000796 9.68501 2.30924 0.95636 0 0.18287 0.04162 0.15707 0.03575 1.77107 0.12583 1.52128 0.10808 56155.450002 0.000961 6.43780 1.27355 0.97289 0 0.22223 0.04097 0.18976 0.03498 1.43067 0.10266 1.22451 0.08786 56155.451773 0.000810 6.37628 1.25177 0.97857 0 0.26657 0.04879 0.22874 0.04186 1.69973 0.12072 1.45665 0.10345 56155.453498 0.000914 7.13119 1.47671 0.97468 0 0.21294 0.04143 0.18161 0.03533 1.51853 0.10770 1.29752 0.09202 56155.455364 0.000952 6.80779 1.39753 0.98176 0 0.21103 0.04061 0.18090 0.03481 1.43667 0.10263 1.22929 0.08781 56155.457152 0.000836 7.82345 1.73368 0.97578 0 0.20995 0.04403 0.17919 0.03757 1.64257 0.11769 1.40437 0.10062 56155.459542 0.001554 7.44449 1.25202 0.98696 0 0.19499 0.03094 0.16649 0.02642 1.45163 0.08089 1.24024 0.06911
