/* ** ** 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 54497.721907 0.000608 0.23350 0.04171 0.80952 0 2.69980 0.23528 2.34014 0.20390 0.63039 0.09830 0.54631 0.08520 54497.723178 0.000663 0.20533 0.03659 0.78166 0 2.83588 0.22839 2.45587 0.19779 0.58230 0.09256 0.50460 0.08019 54497.724338 0.000498 0.28993 0.05232 0.75581 0 2.85120 0.26480 2.45518 0.22801 0.82665 0.12790 0.71162 0.11010 54497.725568 0.000732 0.19625 0.03251 0.75099 0 2.99093 0.21645 2.59630 0.18788 0.58697 0.08747 0.50895 0.07585 54497.727113 0.000813 0.26397 0.04179 0.75093 0 2.49408 0.19098 2.15092 0.16471 0.65836 0.09124 0.56872 0.07883 54497.729431 0.001409 0.13610 0.03293 0.78351 1 3.02450 0.24697 0.75938 0.06201 0.41164 0.09375 0.10341 0.02355 54497.731740 0.000901 0.25959 0.06655 0.66129 1 2.95455 0.34378 0.73871 0.08593 0.76698 0.17522 0.19111 0.04366 54497.733498 0.000857 0.24448 0.06149 0.76271 1 2.85990 0.31369 0.71885 0.07885 0.69918 0.15825 0.17569 0.03977 54497.735343 0.000988 0.19765 0.04966 0.79412 1 2.91481 0.29570 0.73277 0.07434 0.57611 0.13242 0.14423 0.03315 54497.737362 0.001002 0.21109 0.05237 0.79710 1 2.71672 0.28413 0.68357 0.07149 0.57348 0.12901 0.14460 0.03253 54497.739207 0.000842 0.26627 0.06846 0.74138 1 2.68966 0.30610 0.67803 0.07716 0.71616 0.16512 0.18058 0.04164 54497.740877 0.000828 0.28259 0.07360 0.71930 1 2.66422 0.32249 0.66898 0.08097 0.75289 0.17363 0.18938 0.04367 54497.742678 0.000973 0.23015 0.05844 0.73134 1 2.76253 0.30632 0.69318 0.07687 0.63580 0.14524 0.15990 0.03653 54497.744886 0.001235 0.17105 0.04212 0.75294 1 2.85885 0.26304 0.71549 0.06583 0.48899 0.11171 0.12243 0.02797 54497.746731 0.000610 0.37847 0.09983 0.78571 1 2.65336 0.38027 0.66262 0.09496 1.00422 0.22238 0.25098 0.05557 54497.749505 0.002164 0.18398 0.03400 0.66524 1 3.02384 0.20200 0.75502 0.05043 0.55632 0.09586 0.13863 0.02389 54497.788705 0.000127 0.14544 0.08225 0.77268 0 2.16622 0.55336 1.81755 0.46378 0.31505 0.15897 0.26420 0.13350 54497.790918 0.000281 0.29668 0.09021 0.72420 0 3.40765 0.57887 1.69091 0.28757 1.01097 0.25494 0.49768 0.12561 54497.794787 0.000648 0.24881 0.04519 0.73455 0 4.47120 0.40271 2.22296 0.19999 1.11248 0.17543 0.55220 0.08712 54497.796308 0.005098 0.15667 0.03024 0.42615 1 2.39482 0.17456 0.54879 0.04001 0.37521 0.06706 0.08603 0.01537 54497.796734 0.001299 0.24251 0.03296 0.73867 0 4.04334 0.28287 2.02704 0.14182 0.98056 0.11425 0.49100 0.05722 54497.802903 0.001467 0.19550 0.04934 0.71287 1 2.43503 0.26454 0.55898 0.06072 0.47606 0.10845 0.10914 0.02486
