/* ** ** 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 54380.641722 0.000862 0.12619 0.00974 0.99664 0 13.50651 0.34571 10.49577 0.26863 1.70438 0.12417 1.32571 0.09657 54380.643487 0.000903 0.11782 0.00903 0.99359 0 13.89301 0.34330 10.76492 0.26598 1.63686 0.11879 1.26942 0.09212 54380.645466 0.001076 0.11194 0.00828 0.98031 0 13.29322 0.30714 10.33071 0.23868 1.48804 0.10459 1.15660 0.08129 54380.708371 0.000845 0.13072 0.01020 0.98288 0 13.42961 0.34949 10.39574 0.27052 1.75557 0.12909 1.35849 0.09990 54380.710194 0.000978 0.10934 0.00824 0.98225 0 14.34095 0.33707 10.94973 0.25736 1.56811 0.11234 1.19600 0.08568 54380.712191 0.001019 0.12339 0.00871 0.99909 0 13.83957 0.32544 10.57167 0.24858 1.70769 0.11364 1.30567 0.08688 54380.774896 0.000703 0.15385 0.01181 0.98765 0 13.52346 0.37924 10.81785 0.30335 2.08064 0.14864 1.66321 0.11879 54380.776514 0.000914 0.11633 0.00875 0.98734 0 13.75340 0.33556 10.98840 0.26809 1.59987 0.11384 1.27858 0.09098 54380.778652 0.001224 0.13308 0.00830 0.98743 0 13.55515 0.28764 10.76789 0.22849 1.80394 0.10582 1.43233 0.08401 54380.842388 0.000833 0.12427 0.00945 0.99306 0 14.34718 0.36476 11.16500 0.28383 1.78288 0.12771 1.38846 0.09945 54380.844074 0.000854 0.12461 0.00935 0.98983 0 14.13302 0.35418 11.00836 0.27587 1.76119 0.12454 1.37214 0.09703 54380.846083 0.001155 0.12065 0.00794 0.96661 0 14.64377 0.30971 11.43681 0.24189 1.76672 0.11014 1.37934 0.08598 54380.909080 0.000859 0.11520 0.00898 0.98653 0 14.70097 0.35990 11.49766 0.28147 1.69359 0.12539 1.32445 0.09805 54380.910654 0.000715 0.14456 0.01101 0.99190 0 14.51837 0.39298 11.28067 0.30533 2.09875 0.14940 1.62802 0.11587 54380.912625 0.001256 0.12703 0.00799 0.97696 0 14.04682 0.29155 10.93519 0.22695 1.78433 0.10592 1.38725 0.08236
