/* ** ** 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 59298.097477 0.001583 0.17816 0.04513 0.68807 1 1.19007 0.11344 0.57112 0.05445 0.21203 0.04976 0.10186 0.02389 59298.100382 0.001322 0.19234 0.04854 0.78022 1 1.18866 0.12835 0.57445 0.06202 0.22863 0.05215 0.11056 0.02521 59298.102546 0.000842 0.30001 0.07860 0.79310 1 1.19381 0.15399 0.57392 0.07402 0.35816 0.08167 0.17065 0.03892 59298.105509 0.002121 0.19258 0.03695 0.77100 1 1.29496 0.10394 0.61751 0.04956 0.24938 0.04347 0.11895 0.02073 59298.167974 0.001482 0.14857 0.03642 0.77451 1 1.44905 0.13402 0.67293 0.06223 0.21528 0.04887 0.09982 0.02266 59298.171519 0.002063 0.20012 0.04386 0.77280 1 1.03387 0.09617 0.47742 0.04440 0.20690 0.04106 0.09555 0.01896 59298.214321 0.002789 0.17811 0.03222 0.75186 1 1.38052 0.10100 0.57542 0.04209 0.24588 0.04069 0.10334 0.01709
