/* ** ** 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 56139.474764 0.000752 10.85478 2.86030 0.97692 0 0.17118 0.04342 0.14348 0.03639 1.85807 0.13272 1.56332 0.11165 56139.476422 0.000900 8.50614 1.91212 0.97749 0 0.18213 0.03883 0.15464 0.03297 1.54918 0.11036 1.31279 0.09352 56139.478158 0.000836 7.68002 1.71034 0.96886 0 0.21533 0.04536 0.18256 0.03846 1.65377 0.11962 1.40216 0.10141 56139.479830 0.000836 7.17409 1.49875 0.95848 0 0.23460 0.04601 0.19880 0.03899 1.68306 0.12111 1.42781 0.10274 56139.481399 0.000732 9.51257 2.25827 0.95257 0 0.20579 0.04660 0.17453 0.03952 1.95762 0.13945 1.66056 0.11829 56139.483765 0.001635 6.82673 1.03319 0.97876 0 0.23274 0.03306 0.19832 0.02817 1.58887 0.08292 1.35355 0.07064
