/* ** ** 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 55983.496519 0.000567 6.34163 1.27583 0.96429 0 0.41206 0.07745 0.33091 0.06219 2.61316 0.18747 2.09296 0.15014 55983.497749 0.000663 10.83410 2.70865 0.95633 0 0.21089 0.05051 0.16690 0.03998 2.28478 0.16390 1.80625 0.12958 55983.498976 0.000564 9.67689 2.32605 0.97949 0 0.26908 0.06173 0.21384 0.04906 2.60388 0.18680 2.07104 0.14857 55983.500179 0.000639 12.52290 3.36685 0.95023 0 0.19074 0.04945 0.15138 0.03925 2.38855 0.17011 1.89580 0.13502 55983.501562 0.000744 7.56765 1.64183 0.96109 0 0.26752 0.05476 0.21148 0.04329 2.02452 0.14566 1.59736 0.11492 55983.502914 0.000608 6.57591 1.34464 0.96667 0 0.37252 0.07129 0.29462 0.05638 2.44969 0.17651 1.94108 0.13986 55983.504149 0.000628 18.49504 6.16503 0.98157 0 0.12682 0.04127 0.09961 0.03243 2.34556 0.16902 1.84995 0.13329 55983.505440 0.000663 7.18130 1.50173 0.97380 0 0.30884 0.06057 0.24454 0.04796 2.21785 0.16096 1.75556 0.12742 55983.506866 0.000764 8.54078 1.70367 0.96970 0 0.29926 0.05669 0.23683 0.04486 2.55595 0.15975 2.02070 0.12629
