/* ** ** 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 55149.521165 0.000451 0.27670 0.01012 1.00000 0 50.88508 0.86189 45.89572 0.77736 14.07974 0.45620 12.70015 0.41146 55149.522076 0.000460 0.26336 0.00966 1.00000 0 52.16170 0.86883 47.10228 0.78446 13.73744 0.44865 12.40370 0.40503 55149.522973 0.000437 0.27801 0.01017 1.00000 0 51.80298 0.88273 47.12392 0.80300 14.40168 0.46610 13.10083 0.42400 55149.523859 0.000448 0.27850 0.01041 1.00000 0 49.64444 0.85625 45.15161 0.77876 13.82604 0.45843 12.57494 0.41695 55149.524784 0.000477 0.25573 0.00927 1.00000 0 51.55476 0.84192 46.88177 0.76561 13.18435 0.42670 11.98924 0.38802 55149.525722 0.000460 0.28028 0.01033 1.00000 0 48.80594 0.83981 44.38874 0.76380 13.67957 0.44598 12.44150 0.40562 55149.526628 0.000446 0.27133 0.00996 1.00000 0 51.87420 0.87588 47.17526 0.79654 14.07504 0.45889 12.79995 0.41732 55149.527779 0.000706 0.27575 0.00813 0.99823 0 49.78798 0.68058 45.29033 0.61910 13.72927 0.35882 12.48910 0.32641 55149.547478 0.000749 0.28555 0.00798 0.99623 0 49.21727 0.64595 45.89408 0.60231 14.05414 0.34698 13.10692 0.32360 55149.587417 0.000136 0.29532 0.02418 1.00000 0 45.95076 1.84113 28.62604 1.13692 13.57025 0.96890 8.52480 0.60279 55149.587747 0.000194 0.28495 0.02353 0.98507 0 48.36282 1.88155 20.93128 0.81389 13.78117 1.00359 5.99378 0.43577 55149.588158 0.000217 0.25545 0.02081 0.98667 0 44.03479 1.62371 20.89591 0.76879 11.24861 0.81699 5.31621 0.38599 55149.588571 0.000197 0.22138 0.01789 1.00000 0 47.42290 1.63511 25.93279 0.89277 10.49834 0.76717 5.75857 0.42090 55149.588933 0.000165 0.26333 0.02154 1.00000 0 46.80046 1.76860 26.25305 0.99168 12.32400 0.89428 6.90174 0.50111 55149.589312 0.000214 0.27422 0.01919 1.00000 0 49.01259 1.61013 26.39886 0.86707 13.44042 0.83029 7.23580 0.44687
