/* ** ** 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 55226.285248 0.000362 0.11784 0.01798 0.99200 0 10.24638 0.50651 6.76738 0.33330 1.20744 0.17431 0.80719 0.11598 55226.285986 0.000376 0.13455 0.02057 0.96923 0 9.41633 0.49479 5.81901 0.30563 1.26693 0.18192 0.78673 0.11273 55226.286663 0.000301 0.06771 0.01668 0.97115 0 9.28242 0.55359 5.56048 0.33157 0.62851 0.15018 0.37612 0.08989 55226.287338 0.000367 0.14751 0.02318 0.96850 0 8.99806 0.49610 5.35914 0.29543 1.32731 0.19527 0.78902 0.11609 55226.288128 0.000422 0.11768 0.01829 0.98630 0 9.57296 0.47720 5.72865 0.28553 1.12650 0.16584 0.67396 0.09916 55226.288860 0.000310 0.15641 0.02385 0.99065 0 10.03439 0.57180 6.03638 0.34398 1.56952 0.22197 0.94497 0.13364 55226.289603 0.000434 0.12759 0.01897 0.96667 0 9.23007 0.46133 5.51599 0.27571 1.17765 0.16491 0.70462 0.09867 55226.290474 0.000437 0.11867 0.01820 0.96689 0 9.45025 0.46669 5.65692 0.27938 1.12143 0.16284 0.67184 0.09755 55226.291380 0.000469 0.10094 0.01557 0.99383 0 9.99479 0.46232 5.96896 0.27609 1.00887 0.14848 0.60279 0.08869 55226.292338 0.000489 0.10699 0.01674 0.97041 0 9.17245 0.43559 5.46660 0.25960 0.98139 0.14632 0.58543 0.08730 55226.293290 0.000463 0.12272 0.01862 0.96250 0 8.78802 0.43862 5.24546 0.26179 1.07846 0.15455 0.64369 0.09223 55226.294242 0.000489 0.12093 0.01832 0.95858 0 8.50657 0.41890 5.06440 0.24937 1.02869 0.14739 0.61190 0.08768 55226.295118 0.000388 0.12893 0.02014 0.98507 0 9.65242 0.50457 5.71768 0.29886 1.24450 0.18318 0.73522 0.10818 55226.296007 0.000501 0.11589 0.01693 0.93642 0 9.92218 0.45274 5.87519 0.26806 1.14985 0.15954 0.67922 0.09424
