/* ** ** 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 58229.785455 0.000553 0.17229 0.03541 0.75840 0 3.18219 0.27625 2.61731 0.22721 0.54825 0.10212 0.45093 0.08400 58229.787058 0.001002 0.30025 0.07864 0.69565 1 1.29533 0.16418 0.55529 0.07038 0.38892 0.08915 0.16683 0.03823 58229.789658 0.001569 0.21542 0.05440 0.61111 1 1.26571 0.12359 0.53614 0.05235 0.27265 0.06350 0.11652 0.02713 58229.792723 0.001409 0.20589 0.05117 0.59794 1 1.51866 0.14832 0.65282 0.06376 0.31267 0.07146 0.13508 0.03086 58229.795497 0.001365 0.17009 0.04275 0.65957 1 1.69067 0.16014 0.72801 0.06896 0.28756 0.06694 0.12404 0.02888 58229.797719 0.000857 0.38930 0.10366 0.64407 1 1.24245 0.17492 0.53855 0.07579 0.48368 0.10932 0.20835 0.04709 58229.799608 0.001031 0.26296 0.06707 0.64789 1 1.48741 0.16493 0.64412 0.07140 0.39113 0.08984 0.16943 0.03891 58229.844917 0.000671 0.23878 0.04299 0.78879 0 2.45290 0.21144 2.07628 0.17897 0.58571 0.09257 0.49578 0.07836 58229.846025 0.000437 0.16041 0.03956 0.80132 0 2.70309 0.28362 2.28806 0.24007 0.43359 0.09677 0.36702 0.08192 58229.847200 0.000738 0.20028 0.03478 0.78824 0 2.72407 0.21836 2.30582 0.18483 0.54558 0.08405 0.46182 0.07115 58229.848340 0.000391 0.13748 0.03781 0.76296 0 2.99281 0.32191 2.53329 0.27248 0.41144 0.10416 0.34827 0.08817 58229.849130 0.000399 0.15403 0.04319 0.75362 0 2.60688 0.29041 2.20662 0.24582 0.40153 0.10333 0.33988 0.08746 58229.850463 0.000935 0.20889 0.03271 0.73994 0 2.66834 0.18636 2.25865 0.15774 0.55740 0.07812 0.47182 0.06612
