/* ** ** 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 57046.487330 0.000168 0.23345 0.01891 1.00000 0 35.65978 1.25592 29.05308 1.02284 8.32481 0.60728 6.78746 0.49458 57046.487659 0.000162 0.23686 0.01867 1.00000 0 37.39021 1.29957 30.70254 1.06708 8.85641 0.62653 7.26936 0.51421 57046.487995 0.000174 0.23500 0.01880 0.98333 0 36.66009 1.27741 28.77412 1.00226 8.61505 0.62054 6.77083 0.48761 57046.488351 0.000182 0.23058 0.01847 1.00000 0 35.65608 1.24461 27.21698 0.95003 8.22142 0.59272 6.27410 0.45242 57046.488727 0.000194 0.21249 0.01722 1.00000 0 36.19982 1.22784 27.28272 0.92542 7.69211 0.56607 5.81896 0.42794 57046.489086 0.000165 0.26467 0.02225 1.00000 0 33.70932 1.28992 25.77112 0.98621 8.92179 0.66794 6.81900 0.51061 57046.489448 0.000197 0.21466 0.01680 1.00000 0 35.99133 1.20131 27.58399 0.92067 7.72576 0.54709 5.92461 0.41955 57046.489838 0.000194 0.22178 0.01779 1.00000 0 34.29780 1.17270 26.46879 0.90506 7.60650 0.55212 5.87267 0.42625 57046.490238 0.000205 0.21146 0.01678 0.98592 0 34.94396 1.15835 26.71371 0.88548 7.38909 0.53278 5.64669 0.40717 57046.490709 0.000266 0.23288 0.01541 0.99995 0 35.01269 1.01474 27.05669 0.78418 8.15393 0.48490 6.30225 0.37480
