/* ** ** 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 58227.332636 0.000784 0.30165 0.07860 0.64815 1 1.56102 0.18161 0.73107 0.08499 0.47088 0.10980 0.21952 0.05117 58227.334597 0.001177 0.23558 0.05931 0.70370 1 1.29789 0.14250 0.59469 0.06527 0.30575 0.06927 0.13864 0.03140 58227.336907 0.001133 0.20658 0.05184 0.64103 1 1.67771 0.16192 0.75235 0.07258 0.34658 0.08029 0.15464 0.03581 58227.338824 0.000755 0.40689 0.10995 0.63462 1 1.26503 0.17448 0.57671 0.07951 0.51473 0.11961 0.23356 0.05427 58227.340422 0.000842 0.32519 0.08573 0.62069 1 1.46891 0.18280 0.66208 0.08238 0.47768 0.11101 0.21410 0.04975 58227.342514 0.001191 0.35433 0.07684 0.57072 1 1.50589 0.15307 0.68397 0.06946 0.53358 0.10221 0.24058 0.04607
