/* ** ** 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 56067.042344 0.000804 8.36288 1.91337 0.97482 0 0.20582 0.04471 0.17433 0.03786 1.72121 0.12361 1.45851 0.10473 56067.043834 0.000686 7.23013 1.57485 0.97890 0 0.27793 0.05719 0.23660 0.04868 2.00944 0.14363 1.71069 0.12227 56067.045879 0.001360 12.45022 2.59095 0.97491 0 0.14248 0.02862 0.12080 0.02426 1.77388 0.09645 1.50260 0.08170 56067.106831 0.000706 15.33095 4.56231 0.97951 0 0.13104 0.03783 0.10732 0.03098 2.00890 0.14515 1.64938 0.11917 56067.108179 0.000642 10.31039 2.58080 0.95495 0 0.22054 0.05285 0.18128 0.04345 2.27383 0.16430 1.85945 0.13434 56067.109536 0.000715 7.49857 1.60968 0.95951 0 0.27125 0.05491 0.22322 0.04518 2.03401 0.14534 1.67495 0.11969 56067.110951 0.000700 9.58522 2.33804 0.97521 0 0.21517 0.05016 0.17539 0.04088 2.06242 0.14806 1.67532 0.12026 56067.113107 0.001455 9.69468 1.67834 0.96620 0 0.19747 0.03262 0.16312 0.02694 1.91443 0.09904 1.57518 0.08149
