/* ** ** Swift/XRT hardness ratio for M87. ** 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 54527.351300 0.030390 0.24056 0.04698 0.02963 1 3.43719 0.26140 0.86849 0.06603 0.82686 0.14872 0.20962 0.03770 54527.382620 0.000930 0.21162 0.05392 0.64062 1 3.47798 0.33393 0.88257 0.08475 0.73601 0.17371 0.18529 0.04374 54527.384595 0.000930 0.18602 0.04685 0.73438 1 3.59612 0.33886 0.90231 0.08498 0.66896 0.15623 0.16758 0.03912 54527.386266 0.000741 0.28265 0.07621 0.62745 1 3.21699 0.34834 0.80649 0.08732 0.90927 0.22454 0.22733 0.05616 54527.387777 0.000770 0.29110 0.07715 0.56604 1 3.38760 0.36016 0.84357 0.08970 0.98614 0.23942 0.24652 0.05986 54527.389767 0.001191 0.29162 0.05888 0.62265 1 3.43665 0.28538 0.85402 0.07092 1.00221 0.18444 0.24900 0.04583
