/* ** ** 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 58585.072169 0.000857 0.29905 0.07840 0.61017 1 2.88640 0.32992 0.70265 0.08033 0.86319 0.20364 0.21102 0.04977 58585.073708 0.000596 0.40942 0.11172 0.63415 1 2.97220 0.41214 0.71841 0.09960 1.21687 0.28599 0.29321 0.06891 58585.075059 0.000755 0.35887 0.09273 0.61538 1 2.90991 0.36623 0.70865 0.08919 1.04428 0.23566 0.25410 0.05734 58585.076701 0.000857 0.33338 0.08467 0.54237 1 3.06462 0.32181 0.74206 0.07793 1.02170 0.23625 0.24821 0.05739 58585.078720 0.001162 0.23091 0.05921 0.51250 1 3.25230 0.29862 0.79367 0.07288 0.75097 0.17979 0.18266 0.04372 58585.080463 0.000581 0.39292 0.10572 0.62500 1 3.36091 0.47989 0.81991 0.11707 1.32057 0.30117 0.32202 0.07342
