/* ** ** 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 55981.024663 0.000530 6.93194 1.43322 0.98361 0 0.37657 0.07305 0.31950 0.06196 2.61039 0.18672 2.20975 0.15805 55981.025858 0.000666 10.79099 2.79109 0.95217 0 0.19615 0.04875 0.16709 0.04151 2.11670 0.15179 1.80708 0.12958 55981.027036 0.000512 6.19509 1.21473 0.96610 0 0.43977 0.08029 0.37329 0.06815 2.72440 0.19475 2.32072 0.16590 55981.028173 0.000625 9.26385 2.18455 0.97222 0 0.23931 0.05380 0.20489 0.04606 2.21693 0.15774 1.89753 0.13501 55981.029348 0.000550 9.82187 2.47125 1.00000 0 0.24770 0.05973 0.21177 0.05107 2.43287 0.17473 2.08003 0.14939 55981.030453 0.000556 8.65082 1.96830 0.97396 0 0.29361 0.06348 0.24873 0.05378 2.53999 0.17992 2.15722 0.15280 55981.031564 0.000556 6.28154 1.24310 0.98438 0 0.39130 0.07219 0.33457 0.06172 2.45799 0.17608 2.10163 0.15055 55981.032777 0.000657 7.48932 1.58002 0.96916 0 0.28364 0.05630 0.24197 0.04803 2.12431 0.15186 1.80383 0.12895 55981.034423 0.000990 8.34739 1.32316 0.96491 0 0.33484 0.05026 0.28318 0.04251 2.79505 0.14243 2.37145 0.12083
