/* ** ** 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 59366.195731 0.000998 0.10551 0.00813 0.99130 0 12.11407 0.28535 10.84610 0.25550 1.27810 0.09379 1.14443 0.08398 59366.197768 0.001039 0.10683 0.00835 0.98050 0 11.40992 0.27256 10.26602 0.24521 1.21892 0.09072 1.09707 0.08165 59366.199738 0.000932 0.12072 0.00944 0.98447 0 11.27072 0.28583 10.14319 0.25724 1.36062 0.10067 1.22328 0.09052 59366.201657 0.000987 0.11238 0.00876 0.97361 0 11.52052 0.28220 10.39324 0.25459 1.29470 0.09581 1.16801 0.08643 59366.203610 0.000966 0.10822 0.00838 0.97904 0 12.22579 0.29527 11.00685 0.26584 1.32305 0.09734 1.19080 0.08762 59366.205994 0.001418 0.10821 0.00703 0.98373 0 11.48598 0.23535 10.32449 0.21154 1.24292 0.07663 1.11708 0.06887 59366.245690 0.000868 0.12003 0.00899 0.99333 0 12.07867 0.29896 11.19685 0.27714 1.44980 0.10252 1.34452 0.09507 59366.247368 0.000810 0.12875 0.00978 0.98214 0 12.05623 0.30792 11.22464 0.28668 1.55222 0.11107 1.44475 0.10338 59366.249854 0.001675 0.12105 0.00661 0.98100 0 11.96857 0.21315 11.15333 0.19863 1.44885 0.07479 1.35016 0.06970
