/* ** ** 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 56091.563334 0.000535 14.82471 4.41174 0.97838 0 0.17305 0.04996 0.14659 0.04232 2.56547 0.18531 2.17149 0.15686 56091.564402 0.000532 10.11379 2.48898 0.97283 0 0.25776 0.06072 0.21992 0.05181 2.60689 0.18572 2.22333 0.15840 56091.565489 0.000556 10.98393 2.99890 0.96354 0 0.23164 0.06104 0.19751 0.05204 2.54426 0.18169 2.16430 0.15455 56091.566557 0.000512 11.52817 3.12857 0.99435 0 0.22889 0.05988 0.19281 0.05043 2.63870 0.19061 2.23319 0.16132 56091.567550 0.000480 9.06701 2.20303 0.97590 0 0.31994 0.07433 0.27078 0.06289 2.90089 0.20643 2.45941 0.17500 56091.568562 0.000532 8.25326 1.85595 0.97826 0 0.31262 0.06665 0.26711 0.05695 2.58016 0.18451 2.20350 0.15757 56091.569575 0.000480 15.28020 4.73011 0.98193 0 0.18561 0.05589 0.15851 0.04773 2.83615 0.20359 2.42505 0.17407 56091.570544 0.000489 12.42322 3.43460 0.98225 0 0.22735 0.06073 0.19306 0.05155 2.82438 0.20146 2.39474 0.17082 56091.571974 0.000940 8.66576 1.48799 0.96923 0 0.30479 0.04973 0.26050 0.04251 2.64121 0.14126 2.25611 0.12066
