/* ** ** 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 56057.479530 0.000379 4.73752 2.68238 0.92366 0 0.29027 0.15014 0.06491 0.03344 1.37517 0.31669 0.32372 0.07414 56057.480586 0.000677 4.61689 1.62001 0.91026 0 0.50792 0.16256 0.09758 0.03123 2.34502 0.33728 0.46396 0.06656 56057.481868 0.000605 5.04606 1.82989 0.93780 0 0.52287 0.17430 0.10073 0.03358 2.63843 0.37671 0.50648 0.07231 56057.483158 0.000686 15.51006 9.22122 0.92405 0 0.15356 0.08866 0.02946 0.01701 2.38177 0.33762 0.45636 0.06469 56057.484457 0.000613 17.07419 10.14761 0.90566 0 0.15931 0.09198 0.03114 0.01798 2.72009 0.38355 0.52864 0.07454 56057.485432 0.000362 4.63426 2.60719 0.96000 0 0.36966 0.19040 0.07146 0.03682 1.71309 0.38764 0.33016 0.07471 56057.486133 0.000339 20.48156 20.95688 0.94872 0 0.09938 0.09938 0.01926 0.01926 2.03542 0.44105 0.39100 0.08473 56057.486810 0.000339 8.98005 6.66342 0.93162 0 0.21198 0.14989 0.04088 0.02891 1.90360 0.42818 0.36553 0.08222 56057.487478 0.000330 6.08698 3.77468 0.92105 0 0.32380 0.18695 0.06196 0.03577 1.97095 0.44599 0.37732 0.08538 56057.488120 0.000312 6.10914 3.91699 0.95370 0 0.32997 0.19829 0.06289 0.03779 2.01586 0.45077 0.38900 0.08698 56057.489017 0.000584 21.79851 15.73254 0.94059 0 0.12239 0.08655 0.02343 0.01657 2.66797 0.38552 0.51658 0.07464
