/* ** ** 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 54511.459126 0.000637 0.22099 0.04054 0.78636 0 2.68294 0.23415 2.32412 0.20286 0.59290 0.09566 0.51497 0.08307 54511.460388 0.000625 0.25591 0.04606 0.77315 0 2.49215 0.22277 2.15099 0.19225 0.63776 0.09964 0.54926 0.08576 54511.461765 0.000752 0.19790 0.03365 0.79874 0 2.85941 0.22297 2.46374 0.19216 0.56586 0.08550 0.48890 0.07389 54511.513421 0.001218 0.20390 0.02601 0.79867 0 2.93928 0.16878 2.43964 0.14008 0.59932 0.06827 0.49699 0.05662 54511.515521 0.000872 0.20453 0.05235 0.65000 1 3.77383 0.35786 0.94199 0.08933 0.77185 0.18350 0.19333 0.04597 54511.517162 0.000770 0.29072 0.07787 0.64151 1 3.02693 0.36102 0.75494 0.09003 0.88000 0.21104 0.21996 0.05274 54511.519355 0.001423 0.25934 0.04930 0.63265 1 3.51138 0.27393 0.87345 0.06815 0.91065 0.15788 0.22684 0.03932
