/* ** ** 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 54307.013796 0.001699 0.16809 0.04072 0.98291 1 1.62788 0.15170 0.41514 0.03869 0.27363 0.06119 0.06957 0.01556 54307.018850 0.003355 0.13275 0.02504 0.98539 1 1.66355 0.10948 0.42287 0.02782 0.22084 0.03904 0.05623 0.00994 54307.080074 0.001307 0.20274 0.04998 0.97778 1 1.80030 0.18678 0.44894 0.04655 0.36499 0.08162 0.09091 0.02033 54307.084083 0.002702 0.13255 0.02586 0.99303 1 1.97026 0.13536 0.49030 0.03368 0.26116 0.04768 0.06497 0.01186 54307.150134 0.004009 0.17962 0.03874 0.99168 1 1.04895 0.09414 0.21234 0.01908 0.18842 0.03696 0.03800 0.00745 54307.214235 0.001438 0.16221 0.03911 0.97980 1 2.06538 0.18625 0.50722 0.04573 0.33503 0.07492 0.08247 0.01844 54307.218244 0.002571 0.18164 0.03270 0.99267 1 1.88198 0.13797 0.46252 0.03388 0.34184 0.05620 0.08423 0.01385 54307.281235 0.001772 0.14997 0.03524 0.99180 1 1.87063 0.16285 0.46330 0.04034 0.28055 0.06122 0.06942 0.01515 54307.285244 0.002237 0.20118 0.03911 0.97210 1 1.70622 0.13799 0.42386 0.03428 0.34326 0.06068 0.08550 0.01511 54307.348389 0.001569 0.19237 0.04599 1.00000 1 1.23074 0.12014 0.40777 0.03979 0.23676 0.05167 0.07778 0.01697 54307.352398 0.002440 0.19087 0.03584 0.99823 1 1.28981 0.09864 0.42563 0.03255 0.24618 0.04222 0.08110 0.01391 54307.414995 0.001511 0.17189 0.04187 1.00000 1 1.82627 0.17643 0.45000 0.04345 0.31392 0.07020 0.07692 0.01720 54307.419004 0.002498 0.18403 0.03459 0.98256 1 1.77915 0.13674 0.43644 0.03356 0.32741 0.05616 0.08047 0.01380
