/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 57426.185693 0.000538 0.12312 0.00950 0.98925 0 19.24020 0.48750 17.37371 0.44017 2.36879 0.17270 2.13904 0.15593 57426.186677 0.000446 0.14697 0.01143 0.99351 0 19.45830 0.54202 17.48794 0.48712 2.85974 0.20769 2.57123 0.18669 57426.187585 0.000463 0.13731 0.01056 0.97500 0 20.36338 0.54230 18.45922 0.49157 2.79604 0.20166 2.53343 0.18273 57426.188529 0.000480 0.13535 0.01059 0.97590 0 19.96464 0.53084 17.78459 0.47284 2.70230 0.19886 2.40595 0.17703 57426.189434 0.000425 0.15195 0.01176 0.99320 0 19.83841 0.55730 17.80597 0.50019 3.01443 0.21742 2.70695 0.19524 57426.190320 0.000460 0.13475 0.01062 0.99371 0 20.20340 0.53895 18.31069 0.48843 2.72243 0.20189 2.46921 0.18312 57426.191254 0.000475 0.13753 0.01061 0.97561 0 19.89907 0.52808 17.98595 0.47734 2.73680 0.19819 2.47126 0.17896 57426.192189 0.000460 0.14031 0.01098 0.98742 0 20.02601 0.54505 17.77490 0.48373 2.80979 0.20621 2.49533 0.18311 57426.193098 0.000448 0.13720 0.01095 1.00000 0 20.09268 0.54623 18.06840 0.49112 2.75666 0.20688 2.47943 0.18614 57426.193997 0.000451 0.14193 0.01087 0.98077 0 20.35810 0.54607 18.36182 0.49247 2.88938 0.20735 2.60929 0.18723 57426.194857 0.000408 0.15810 0.01221 1.00000 0 19.65065 0.56489 17.79903 0.51165 3.10667 0.22267 2.81583 0.20176 57426.195676 0.000411 0.15812 0.01227 1.00000 0 19.61638 0.56086 17.60145 0.50322 3.10182 0.22379 2.78321 0.20074 57426.196509 0.000422 0.15577 0.01200 0.98630 0 19.61716 0.55693 17.70159 0.50249 3.05568 0.21893 2.75717 0.19755 57426.197354 0.000422 0.15057 0.01175 0.99315 0 20.05517 0.55972 18.04670 0.50362 3.01966 0.22011 2.71437 0.19787 57426.198520 0.000744 0.13410 0.00841 0.98444 0 19.58236 0.41842 17.66781 0.37749 2.62599 0.15479 2.37273 0.13981
